open in one of the most dramatic victories in modern tennis. she beat 19—year—old leylah fernandez of canada in two sets — 6-4, 6-3. raducanu only made it into the tournament as a qualifier. and we stay with that story — emma raducanu's win at the final of the us open. raducanu only made it into the tournament as a qualifier, but she won the title without dropping a single set. she's the first british woman to win a grand slam title in 44 years. a stunning victory, says our reporter lizzie greenwood—hughes at the bbc sports centre. people are saying how much they love this game

the way these two teenagers played has been incredible. the commentators are saying they have nerves of steel. she had to come through qualifying. she has everything. she is such a talent.

she has done this like a seasoned pro. an incredible scoreline for anyone to win, a qualifier with so little experience. i know i sound over—the—top but this final has been amazing. this week on the show... upside down in nairobi. the city of love's freewheeling new ideas. and treading carefully in georgia's abandoned spaces.

kenya, it's a country bursting with natural beauty, the wildlife here is world beating, the bush is unspoiled and pristine, and sunsets will take your breath away. it's a bit different

in the capital, but hidden in this maze of dusty backstreets, there is something truly special. welcome to the mighty jambo circus academy. these are kenya's best—known acrobats. in normal times, they would be off touring the world. thanks to the pandemic, they have been stuck in nairobi for a year and a half. this is probably the most action i have ever seen happening per square metre in my entire life. it's incredible.

in years gone by, the performers here, from tumblers to contortionists, have travelled across the planet showing off their incredible skills. in 2020 though, thanks to the pandemic, they only had one booking. this year, they've got nothing, no money coming in whatsoever. the first time we had the booking of the —— to close down the school, people were confused, not knowing when they would come back. the senior acrobats have their own businesses but the young ones, the young generation, the ones that are starting, they have to keep on training but not knowing when. that must be frustrating. everything is just shut. i bet that is a loss of income for the academy? it is bad for the academy and for the individuals

because they depend on this. everybody, the seniors, their families depend on acrobatics, and when they tell us not to come together for practising, something like that, it's so difficult for us. matthias invites me for an early morning run to show me how they have been keeping in shape without a show to work towards, and it starts at 5:30am, every single day. a whole country of good runners, yeah? we are runners. i'd rather be an acrobat. it must be frustrating for you. really frustrating, not knowing when this thing will be over. so many restrictions, so that will be very confusing, not knowing when i can

try to live a life. do you think it affects their motivation? it affects their motivation, but these people are really determined to make their life count. they train for the new job, but the problem is they don't get an income for that. i wave the runners on the way, bouncing up the road, and i think about how much positive energy they are carrying with them. but if the destruction carries on for much longer, the biggest impact could be on their outreach work. mightyjambo runs a number of programmes to help kids in nairobi, not least with acro—education services, which pays for children's schooling. it's a precious resource in a country that has a problem with high unemployment and with poverty. why do you like coming to the school here?

no rope necessary, that's amazing! any advice you can give me that you learned here? since the time they have come here, i have seen a big difference, they have a lot more confidence and they are

willing to do better. i am very proud because the time they are here, i know they are under care. i know they are in a safe place when i go to myjob, so i am very grateful for this place. and the things. and good luck to mighty jambo for the second half of this year. i've got everything crossed that bookings start to roll in again soon. ok, here is our pick of some of the best things to see and do around the world in the next few weeks. london's chelsea flower show

is happening in september this year, for the first time in its history. the organisers claim it's the world's most prestigious horticultural event, and it usually fills with the colours of spring and summer. the change in season was forced by the pandemic, and it could mean a much more autumnal feel than usual. in recent years, nuit blanche, or white night, has become an autumn fixture on the arts calendar of paris. it's a citywide celebration of the city, a celebration that goes on from 7pm to 7am on october 2nd. public transport stays open all night to help you see as much as possible. this year it's themed around the outdoors, for obvious reasons. hundreds of museums across the us throw open their doors forfree on september 18 as the annual smithsonian magazine museum day returns. it's not only museums — zoos, and cultural centres across all 50 states are included as well. you need to sign up online, and crucially, only us citizens can book tickets. china's midautumn

festival begins on the 19th of september. it's got a history dating back 3000 years when the emperors worshipped the moon for a bountiful harvest. adherents believe the moon is at its brightest during the festival. a great place to see it is beijing's beihai park. the crowds heading there like to take a moonlight cruise on the lake with locally bought moon cake, and with tea. still to come on the travel show... the big ideas that could clean up paris. and the former asylum exciting america's urban explorers — so don't go away! our next port of call this week finds us in france, which has used lockdown to think again about how its people work, play, and travel in their capital city. it has enacted sweeping car

bans, paving the way for more of the same across europe, as we have been finding out.

translation: eleanor: next up, we're crossing to the us and the city of milledgeville in georgia, which used to be home to one of the biggest psychiatric hospitals in the world. in recent times, the half—abandoned site has become a honeypot for urban explorers. william lee roberts, who is from the state, has been to take a look. sprawling, overbearing and derelict, these 200 buildings once made up one

of the largest and most notorious state—run psychiatric hospitals in the world. based in milledgeville, a small town less than 100 miles from atlanta, the central state hospital's dark legacy is infamous with local residents. founded in the 19th century as the georgia state lunatic, idiot and epileptic asylum, a lack of funding and a primitive approach to mental health led to brutal treatments and, at times, deteriorating conditions. it's strange but when i was a little kid and i was misbehaving, my father would threaten me by saying "i'm gonna send you down to milledgeville" and i would shut up. but to be here voluntarily all these years later, it feels a little wrong. a small section of the hospital is still in operation. there are still patients here at central state hospital — over 300 of them — and it's important to remember that this is still an active hospital. it's very disrespectful to them and to their treatment to try to come out here and either break into the buildings or quote

unquote "hunt for ghosts". beyond the working hospital, most of the estate is now in disrepair and in recent years, dark tourism has attracted an influx of urban explorers keen to record milledgeville�*s sinister legacy. but structural damage and reports of decades—old asbestos mean that the interiors of most of the buildings are officially off—limits. roofs have caved in, windows have been boarded up and staircases have collapsed. but perhaps more powerful than the actual buildings are the thousands of graves of former patients — a chilling reminder that many people entered milledgeville but never left. so when you look at the stakes here, they all do have numbers on them and it's sort of a misnomer that we don't know who they all are.

we do know every person is who's buried here — the numbers were for privacy purposes. many locals have relatives who either worked at the hospital or were admitted there. for some, not enough is being done to honour their memory. i feel sorry for my great—grandmother — she was in the building right there. if i can't relive and memorialise her and what she did here, at least you could memorialise where she stayed and the hospital that she spent her entire life over the years, racism, sexism and what is now viewed as a rudimentary, if not brutal, approach to treating patients with mental health issues meant that by the 1960s, the hospital's population had swollen to over 12,000 patients. so my great—grandfather sent his wife, betty stubbs, to central state, and i'm

of the opinion that she had post—partum syndrome and had to live here for almost 30 years, either pretending that she was not normal so that she could cope, orjust living in a fog. 1899. 1904. these are the original trustee reports. 1950, there were 10,000 patients here. sadly, a lack of staff and resources meant conditions declined rapidly and the asylum became notorious for its mistreatment of those admitted. so this was for a lobotomy — doctor fisher's lobotomy picks. they went into the eye — orbital socket of the eye and deadened the front part of the brain. but it was real brutal, it really — i think it hurt more than it helped. we've come a long way since then and kari hopes a new museum will remind people how different our approach

to mental health is today. with fields like psychiatry and psychology, as we learn more, we know more, we can do more. as we start to understand the brain chemistry and sort of the human anatomy, we can better help people and help them live successfully, so it's important to remember the history of where we came from and how we've continued to grow as a society and in the medical profession. local authorities now run a tour for those curious about the hospital's dark past. central state hospital is georgia's oldest and largest state psychiatric hospital. i think our tourfills a gap for local residents in milledgeville because the hospital has been something that has been here for a long, long time. i find that people often have a sense in their own mind of what they think it was like but when they come, it's an opportunity for them to really learn about the size, the scope and the humanity involved in the hospital campus. well, i think history is important because if you don't

know where you came from, you're not going to know where you go in the future, and it's extremely important for the people who worked here, for the family members that were patients here and for researchers in the future to know what went on here. the people i've met today have driven home the importance of remembering the patients who lived here and the thousands who died. acknowledging them and what happened is uncomfortable but to me, it feels like the right thing to do. well, that's all for this week but coming up next week — we're in argentina, exploring a haunting city submerged beneath a lake for 30 years that's now slowly re—emerging into the sunshine. imagine living in these houses and all of a sudden, the water is slowly starting to creep up. ten metres! this place is wild! and remember, you can join our adventures by following us on social media — we are on all the regular platforms. and we've got quite a library of inspirational content to inspire you when we can all travel again. from me, mike corey,

and the rest of the travel show team here in kenya, it's goodbye. hello. saturday brought a return to drier, brighter weather across much of the uk with skies like this. with the exception of the heavy rain in northern scotland, similar day to come on sunday for much of the uk. minus the heavy rain in northern scotland with the addition of rain moving into wales from this

weather system approaching from the southwest. it will be turning wetter here as the day goes on. as the day begins, it will be a cooler start, it has been turning fresher from the north and there will be a lot of cloud around in scotland, hill fog and that cloud will slip south into northern england and with it, there will be a few light showers and at the same time northern and western scotland brighten up during the day. a few sunny spells in northern ireland as there will be across east anglia in southeast england. cloud increasing in the midlands and especially in southwest england and wales. still a bit of uncertainty about the progression of this rain and it will impact parts and especially cornwall and devon and looks like it will cover much of wales by the time we get into the evening and temperatures for the most part into the teens to low 20s are some in east anglia

and southeast england. during the evening, rain my push into parts of the midlands especially the west midlands, may fringe into merseyside, and perhaps effecting some in southwest england overnight and into monday morning. the clearest skies will be in scotland, northern ireland and northern counties in northern england with a much cooler night to come with temperatures quite down into single figures with some sunshine as monday starts. some uncertainty on monday about how far north this rain might get and might slip a little bit further on the western side of the uk, may be reaching towards the southern parts of scotland later in the day but the driest weather will be further east with a good deal of bright or sunny spells. with uncertainty about how far north rain will get, it will gradually clearly from eastern parts on tuesday. brighter, sunnier conditions following him behind with the few showers and spots of rain in parts of northern ireland and scotland. and then after that, looks as if we'll get up a couple of drier dates, many drier days before we see another atlantic weather system bearing down on us bringing some rain on thursday night into friday on the current timing. so, the main story about this week's weather then, we are going to see a chance of rain depending on where you are, earlier in the week and then largely dry in midweek before the chance of rain coming back again later in the week.
