inside museums, places i've loved ever since i was a boy. and during my working life, i've witnessed something astonishing how radically they've changed. the days of museums as grand, intimidating treasuries for dusty objects, they're long gone. they're becoming much more dynamic and inclusive places, less solemn, less elitist, and less west—centric, too. museums, i believe, are really having a moment, and that's what i want to explore. what i am looking for is something weird, something different. i feel you've succeeded, inci... she's one of the greatest female artists of the 20th century. so what happened 7 because she kind of, like, drops off the map. she was a woman, and she was a muslim... it's an exciting time to be interested in museums and visual art, because a great shake—up of art history is underway, which is why i've come to istanbul, that mesmerising megalopolis that straddles two continents,

europe and asia. and the interplay between western and turkish art is a fundamental part of the extraordinary collection of this place, istanbul modern. i'm in turkey's biggest city, istanbul. in many ways, the story of istanbul is the story of the bosphorus strait, the waterway that divides the city and has made it a key meeting place for centuries. the brand—new home of istanbul modern acknowledges this with an impressive open—plan ground floor that connects the city with the water. and i've been given special access to the museum as the team make final preparations ahead of its opening. any new museum needs a gifted

architect to create it. and in the italian renzo piano, istanbul modern has hired one of the best. because piano's renowned internationally for his elegant structures, such as london's shard, and cultural buildings, from the pompidou in paris to the whitney in new york, are his speciality. which is why i'm so excited that he's agreed to guide me, via a video call, around his latest creation. hello. i would love to get a sense... ..how do you approach designing a building like this? the first thing inspired by is the content, what you're doing. you're making a museum. what is this for? a museum is a place for people. for people to get together, to stay together. and, you know, the other big thing, very important, is water. before the building is built, you immediately think about water. you immediately think about the ships that are moving around.

then you start to think that, in some way, that building comes from the water. it was almost like a silvery fish jumping out from the water. that's a lovely image. another thing that is more social, is that if you make a building by putting the building on ground, you take it away from public space. so if you make the building fly, the ground floor will become a continuity with the city. if ijust switch around my camera, because as you're speaking we can get a sense, because you've obviously decided to have it glazed on both sides. transparency is because, by lifting the building, you give back the ground floor to the city, to the community. in other words, the building becomes like a flying ship. transparency is notjust aesthetic, it's a social transparency, it's about accessibility.

so i think that people will come to this building, where you are right now. i hope they will come for art, of course, but they may probably come also for another reason, just for the fact that it's so open, so luminous. you've been speaking about it in the most elegant and eloquent fashion. so thank you, renzo. but i should explore this building. i've only got a day, and i need to go and actually explore the building you've talked about so wonderfully, so i should probably ring off, but it's kind of you to make so much time for us, thanks. thank you. thank you, alastair. thank you. enjoy. renzo�*s new building contains an enviable collection of international modern art, which to westerners like me, may feel familiar. but what i'm hoping to discover is work by turkish artists and what it reveals about their national identity. so as the museum is making final preparations, i've been told that there's an artis who was born in istanbul but is now based in los angeles, who's having a really

big moment internationally. refik anadol�*s rise has been meteoric. his spectacular high—tech installations have wowed audiences across the world, and he's created astonishing backdrops for the grammys music awards. i want to peek behind the curtain, to meet this wizard of oz—like visual magician. ah, refik, you're here. how are you? i'm good. oh, this is... this is something else! it feels like we're in the middle of this kind of vortex. i know the piece is called bosphorus. yes. so it feels very watery, like there are currents and a sort of tide around us. this is amazing. thank you. welcome to the data sculpture. yeah... data sculpture. that's the term. 14 years ago, i coined

the term "data painting", the idea that one day data can become a pigment. and this pigment is not a pigment we know, that dries. this pigment shall be always changing, shape shifting based on the data stream itself. what are you referring to? what is the data you're using here? for me, data can be any form of information, but data can be also a form of memory, for example, nature. right now, in this room, we are literally using a real—time weather station which can sense the wind patterns, the speed, humidity, rain. so i like this idea of a live piece of art, and ijust like this idea of making invisible visible through art. so that's interesting because the data is coming in, and it's real time... yes. ..and you and your team make an artistic decision about how to express that data. yes. and i think it's not so different, if you remember the history of art... let's remember monet. so when monet inspired from atmosphere, he was still, i think, imagining similarly, the atmosphere is an abstract form.

but now we are using art, science and technology together to imagine new ways of creativity. so my head's spinning, really, after encountering bosphorus, being plunged into this water and wind, and there's no denying the drama of it. i can see why refik�*s work is just so tremendously popular right across the world. he sees himself as being at the forefront of this new style, this new form of contemporary art, which is clearly ai generated. what i find quite interesting is actually how many old—fashioned aesthetic choices still have to be made. there has to be a decision about how to visualise the data. the simple fact about creating an installation in a curved room with a mirrored floor to create the sense of infinity. so i find that quite heartening too, to have a sense that here's a work that's looking straight at the future, but it also has

one eye, if you like on the art historical past. refik�*s work here may be linked directly to the bosphorus, but it relies on the backrooms of silicon valley in california, a few hours from los angeles, where he now lives and works. decades earlier, another pioneering turkish artist was connecting east with west, and creating her own kaleidoscopic visual worlds. fahrelnissa zeid is a centralfigure in the story of modern turkish art. but despite being born at the dawn of the 20th century, she's only being truly appreciated now. yeah. pleasure to have you here. i'm meeting chief curator oyku ozsoy sagnak to talk me through this — zeid's mesmerising and explosive masterpiece of swirling red and yellow painted shards. the first thing is that sort of sense of it being almost all—encompassing.

it feels like... yeah. ..you could go into it. it's almost like this sort of net that you could get caught up in. but when you sort of take a step back, the way it's been composed, it has these different zones. there's a yellow part with very, very intricate almost thorny parts to it on the left. and then, in the middle, there's this kind of... this void. yeah. this sort of black hole in the centre. yeah. yeah, absolutely. i know it's called my hell... yes. what's she referring to? in fact, fahrelnissa zeid suffered from depression throughout her life. and while sitting in her studio one day, the movement of a fly catch her eye. and then she kind of felt that this movement reflected life. i mean, it's a kind of inspiration for her. so, because all of these many different lines seem to interconnect and go away, and there's an almost random quality to it. but you're saying that on one level, the spark for that was seeing the random movements of a fly buzzing about the studio? yes, absolutely.

she also inspired from different elements. like, you can see these mosaics, like from maybe byzantine or islamic art and architecture, the patterns from ottoman stained glass... with the kind of black leading in between? yes. tell me a little bit about her and thatjourney that comes, ultimately, into this. she was born in 1901 into a very aristocratic ottoman family, and she was one of the first turkish women to go to the art school. in 1928, she travelled to paris, where she studied with the cubist artists. so she was part of the international avant—garde movement, and she kind of defined herself with this cosmopolitan culture. and she got the influence with a variety of cultures, not only the ottoman, turkish, but also mediterranean, all these cultures. she makes all the influences of the abstraction combined with her rich heritage.

but in a way, this is her unique vocabulary. i mean, you can see how she expressed her feelings, creating this very unique universe. so what happened ? because she kind of, like, drops off the map from that western—centric kind of perspective. ithink... she was a woman, and she was a muslim, but she kind of came back to the map again with all these women artists we see all around the world. you can see all these, you know, brush strokes, and then with all these details of the lines, and the colours and the geometrical shapes. it's weird being this close with it, where you do feel you're completely enveloped by it, and it gives you a sense of it... ..proliferating out infinitely as she's doing it, but presumably, as you sort of walk back...

..it�*s quite amazing, isn't it, to sort of see...? yeah, you see the scene is different, and now you see all this kaleidoscopic effect, and it's kind of taking you inside of it. i think i prefer it from here. me too. you need this distance, i think. you see all this constant movement, the energies, and that flowing... i mean, you feel this dynamism. we can find the optimum point to view it from. well, you've deliberately placed it here, haven't you, so that as people enter the gallery... yeah. ..you know, that is what they're seeing? it's kind of creating this mystifying effect. yes. and because it has that slight vortex—like quality... yes. ..it�*s kind of, you're wanting to... ..get sucked into the room... absolutely. ..into the work. i'm exploring istanbul modern�*s sleek, low—slung new waterfront home.

outside and in, there are dramatic pieces by international artists at every turn. but what i want to discover is work by turkish artists, and what that can tell us about this country's complex, beautiful identity. one contemporary turkish artist, whose work i'm keen to know better, is inci eviner, who's agreed to meet me at the museum. so here we are... ..skinless. yes, a kind of room for nomads. i try to create some kind of memory of this nomad's imagination. they are brothers, siblings. they are waiting for dinner time... patting their belly. ..and our table is ready. who's underneath the table? it is my fear, actually. it's come from my childhood. my father was so serious, very authoritarian. it is forbidden to talk on the table. so there is strange things underneath of table. what are these creatures with the heads and the strange wing—like bodies?

it is the typical ottoman miniatures. and then you have more tiny people... yes. my strange people walking and wandering around. where does this imagery... i mean, do you dream it? this is who i am. i don't know. i don't know, but allow me to think about national identity, who i am, and what is this country? what kind of culture? i think there's this delightful energy to this piece, and all of these quite mischievous figures, in some cases, who are dotted around there are many layers, turkish culture and modern period. i think you've got this play between here, the modernist architecture is the rational component... yes, progressive. ..and then you've got these

figures, who are doing... what did you call them? your weird figures? yes. weird figures, every time, come from my mind, i don't know how. there are all of these other elements on top. i mean, there's a dog, and then every now and then you have this... what is it? it's like this kind of meteor, that flashes... there we go! it looks like a wig. wig, yes. what is that? this is the kind of symbol of sexual women, female image... is it? ..for me. but, what i am looking for is something weird. i have to find something different. i am looking for, actually, to create some kind of world where all these different sources, different images, 19th century, 20th century, europe and western, all the local turkish images, come together. you sort of spoke about that your work has a playful quality... yes. ..but also a painful quality. it's true. mostly, i am interested to express the modern disappointment, for example, the girl in the egg shells, this is kind of shelter.

in my imagination, this girl ran away from home. she's, i guess, lost this direction. so all these modern projects failed. it was the future and it promised a better life. and you're saying, actually, that's not the story of the 20th century? yeah, it's true. many dramatic things happen in turkey, especially recently. but at the same time, i needed some joy for the struggling. all of the turkish works i've discovered so far feel somehow enmeshed with this great, vibrant city of istanbul, which straddles the bosphorus strait and the last work i want to consider is no different. it was originally installed nearby, in an old dock warehouse. it's beautiful and intriguing, and a bit of a puzzle. the artist who made it,

gulsun karamustafa, isjoining me on a video call. you can...you can see me, you can hear me? yeah. yeah, i can hear you. so you're in front of my work. you're in istanbul, then? yeah, i'm in istanbul. we're here at the modern. and this isn't a new piece, is it? it is from 1995. it was done for the istanbul biennale. am i correct then in thinking that when you made the work for the biennial then, it was in the same part of the city that's now been redeveloped, and near where istanbul modern stands today? exactly. and this was created in...did you say in a depot, like a sort of old industrial building, a warehouse? it was this working harbour once. you know, ijust sat down for a while thinking and feeling the space. and then i found out that i am in the oldest entertainment district of istanbul. this red light district was there since the byzantium times, since the genoan times, you know.

it never changed, you know. so you have to imagine sailors arriving at the port. these are actually, like, these are nautical ropes that you've used for the installation. but instead of sails, there's actually these ribbons which you've tied to the ropes, many, many of them, in these wonderfully pretty, pastell powder pinks, and white colours. but each of them, i'm looking at the now, is stamped with what look like initials and a date. actually, thinking of this entertainment district, thinking of the sailors, thinking of the harbour and everything, i was listening to a very interesting radio programme then. it was the police radio, and every day there was an announcement, a long announcement about the girls who were lost around istanbul. and that was a long list. i wanted, very discreetly,

to use the initials of these girls and the dates that they had been lost. because in istanbul, when a girl is lost, it means that they end up in somewhere which is not very pleasant. probably the bordell, you know. you mean they end up as sex workers? yes. sometimes... somehow it ends up like this, you know. so you were making a kind of connection, you're fusing a sense of history of the place, over many centuries, with a almost documentary contemporary story about this aspect of society at the time? exactly. and in the end, of course, it ended with these beautiful fluttery pink—white ribbons, maybe they were wearing while they were in their primary schools, or, you know... it's a symbol of this purity and their lost days. it's very powerful.

i felt really very moved actually, in the middle of the conversation. it's a really heartbreaking piece, this. it's wonderful to hear you talk about it. thank you very much indeed. it's a pleasure for me to meet you. and all the best. bye— bye. bye. that was quite an intense interview, actually. it doesn't look it, ostensibly. this is hard—hitting, really, when you think about it. you know, you come up and you're quite beguiled by the prettiness of all of the colours. but when you realise what's going on the initials give you a sense of an individual. but we don't know who these women are, or sadly, in many cases, probably were. and it's actually...it�*s terribly affecting to see it. and i think that that's the hallmark of a really great work of art that manages to say something of true significance about a society while at the same time saying it in a manner that is pithy and readily understandable. this is not esoteric, strange, difficult to get, thanks to its simplicity and the commitment and sincerity

of the artist who's made it. it's a thing that has enormously powerful, i think, powerful beauty, really. it's been a very rich visit. it's been very intense and immensely pleasurable. and there's a lot here that i already knew. i mean, there are clearly lots of big name familiar artists who are in the collection, and great to see them. but i was hoping to discover a lot more beside, and i think i did. this is a collection which focuses on the intricate story of modern and contemporary turkish art. and that story is so sinuous, so surprising, but also quite often, really affecting. as one artist, inci, put it to me, a lot of the stuff i've seen

is as much painful as it is playful. and i think that's a good thing, because here you find something which is reflecting the complexities of the world as it is, notjust in turkey, but universal human experiences. and for me, that's what good art should always aspire to do. for more on inside museums and for our accompanying inside museums artist guide, go to bbc.com. hello.

storm clouds bubbling up. not as many as we saw through yesterday. and still pleasant enough in the sunshine. but through the week ahead, even in the sunny moments, it will start to feel a bit cooler out there. all of us will still see some rain at times, some more than others, admittedly, and it will be a little bit breezier. and that's because we've got low pressure out towards the west at the moment. circulation of cloud here, which will transfer its way northwards and eastwards. this band of cloud is what brought the rain early in the day across east anglia and the southeast and will linger across orkney into the evening. elsewhere, as i said, more sunshine this evening. a few showers particularly through wales, northern england, northern ireland, some of those heavy and thundery. but even this evening, temperatures still in the low twenties. showers for a time through tonight, but they will gradually fade away. heavy rain in shetland clearing too, and tonight will be a little bit fresher again compared with last night. some rural spots down into single figures, but most places still in double figures as we start the monday morning commute. and it will be a sunny one for the vast majority, but quickly clouding over south west england and wales, outbreaks of heavy and potentially thundery

rain pushing in here as we go through the morning. a few showers breaking out through scotland, northern ireland. again, some of those thundery, especially to the northeast of scotland. but longer spells of rain that's in wales will gradually transfer north—west, midlands and in the afternoon into parts of northern england and it could have a big impact. of course, if the cricket is still going. certainly winds freshening up a little bit. but whilst you've got the sunshine out and fewer showers, east anglia and the south east could see temperatures higher than today. elsewhere, roughly on par, feeling cooler where that rain is falling. the rain fizzles into more showery conditions through monday night to the north. but in the south, more persistent rain returns, wales and across central and southern england to take us into tuesday. that may be slow to clear the south east corner on tuesday. other than that, it's back to sunshine, heavy and thundery showers, most frequent during the afternoon in scotland, northern ireland and the north of england. bit of sunshine in between, but temperatures starting to drop, winds going more west to north westerly and that temperature drop will continue further through the second half of the week as our low pressure pushes its way

off towards norway. winds going to a more north or north westerly direction, especially for scotland for a time. so temperatures will drop here. the further north you are, showers most frequent, heaviest for the south, you are, fewer showers at times. temperatures still in the low 20s here and temperatures in the north of scotland, only the mid—teens at highest.

live from london. this is bbc news. crisis at the corporation — a male member of staff is suspended, following claims a presenter paid a teenager for sexually explicit images. it's understood the bbc has been

in touch with the police, in addition to their own enquiries. hello.
