as restrictions are rolled back, cat is on the road in the uk to take a roller—coaster recovery ride. and we're heading to sri lanka to find out about a clean—up campaign along one of the country's historic canals. sites in the world. the roman city of pompeii was destroyed almost 2,000 years ago in 79ad, when nearby

mount vesuvius erupted. metres of ash buried everything, freezing this catastrophic moment in time until its rediscovery in the 16th century. walking through the streets of this ancient city, under the shadow of the active volcano that destroyed it, is actually quite unsettling. pre—pandemic, almost 2 million people came here every year, which put a strain on the site and lead to it almost losing its unesco heritage status in 2015. but it's come a long way since then, partly thanks to a new director, who's made it his mission to protect the site, while also improving the visitor experience. it has always been a site evolving with the times and so it has always been a site to experiment and to try out new approaches —

both for the conservation and for the dialogue with the public — and so this is just continuing. and how do you think this will change the perception of how pompeii used to be? it's really about the vision of the past. it's not only the big families, not only the senators and the ones who got the statues in the forum, and the local authorities, but it's also the slaves and women, who often have — do not appear the same way in the written and official sources, and children, and i mean to see all this complexity of an ancient society, that's really important. the challenge at pompeii is its exposure to the elements and climate change means the site is subject to sudden temperature changes from extreme drought all the way to heavy rain. today, new technologies are helping to preserve this invaluable record

of roman life in the first century. drones are helping to map the site, robots are rebuilding frescos, sensors are monitoring seismic activity, and thermal imaging cameras are helping keep a check on humidity, helping staff to act quickly if potential danger strikes. but the real star of the show is, without a doubt, this four—legged robot that, bizarrely, looks like a dog. good dog. so, paolo, i've got to be honest — i'm geeking out about this. this has got to be the coolest, most elaborate robot i have seen in my life. but tell me about what i am staring at. there is a lot going on here. it's an incredible piece of technology. yeah. it is a machine that is able to move around autonomously, and is able to bring with it some other technologies — other payloads. here, now, you see a computing

power, where we can run our software and a laser scanner that's a special laser scanner that is able to scan while the machine is moving. and the robot itself is able to avoid obstacle, to move autonomously in an environment like — like this ones. and also, since you can upload artificial intelligence and machine learning algorithms on it, you can bring ai wherever it is required — it is needed. by using a combination of technology and a fresh, more inclusive approach to ancient history, the authorities here in pompeii are hoping for a successful tourist season in 2022 after being closed for almost two years. another part of naples set for a boost this summer is the la sanita district, an area that was once partly controlled by the mafia nicknamed la camorra,

here in naples. but thanks to a concerted effort from locals, guesthouses are popping up, the art scene is thriving, and the neighbourhood is being transformed. and the latest tourist attraction leads deep below the streets. it's an archaeological gem that's even older than pompeii, but up till now has been hidden from public view, beneath a private home, and i've been lucky enough to have a sneak preview before the site fully opens to the public later this year. but first, i'm meeting meeting the woman who spent years persuading her husband to share this unique family treasure. during this 26 years, i don't know how many people ask him to open it. but not only kings or prince or archaeologist, or isabella rossellini, i don't know how many people. so i say "maybe we have to open it." and he say "no, no, no —

please alessandra, don't tell me, it is too difficult. come on — no, no, no." following our catch—up, alessandra took me to their property in a seemingly unassuming naples side street to unlock the door to the hidden subterranean marvel. are you ready? an amazing network of tombs that are almost two and a half thousand years old, originally part of a necropolis built outside the city walls back when naples was an ancient greek settlement. on my gosh. yes. look at this. this is the start. the detail! it's full. so you've got to tell me more — this is unbelievable. yes. so, this is maybe one of the most beautiful tomb in the world because everybody came here, the archaeologist,

they had the some reaction. 0ne arrive and say "i want to live here." and so say to my husband "there is an archaeologist that want to live in our tomb. maybe we do something — we must open it." and you see the colour in the architecture, everything is incredible, and we start the restoration from there. so this colour are the same after 2500 years. there is colour everywhere. yeah, i can see. what about this — this person up there? who have we got here? is that medusa? she is the medusa, la gorgona, yeah. she's — she was bad. yeah. and if you go over there you can see that the — she's full of colour, and you can see the teeth and this incredible and it's really unique. and she's the start. it is amazing to think that these terms laid undiscovered for over 2000 years. but thanks to alessandra's powers of persuasion and a lot of hard work, from thisjune, they'll be open

for everyone to see here in naples. right, back to the uk, next. we've been busy touring some of the country's biggest attractions as they prepare to deal with two years of pent—up demand this spring and summer. and this week promises to be quite a roller—coaster. as restrictions relax, i'm travelling across the uk to see how ready the country's top attractions are, to meet the people getting us excited about travel again, and hear their plans for the new normal. today's trip is to staffordshire. and to reach the gates of my chosen attraction, i'm taking the monorail. hello from alton towers, the largest theme park in the uk. now, it's just opened for the season

without any government restrictions in place. and although it's been around for over a0 years, i have a confession to make — this is my first time here. so let's go. sprawling over 900 acres, this was once the residence of the earls of shrewsbury. and being a theme park novice, i've enlisted some help. we're about to do the three rides that they've got up on the stratosphere. shawn sanbrooke is a full—time roller—coaster vlogger with a lot of followers. no worries. shawn, are you a celebrity? i wouldn't say that. i love sharing my adventures. but it's all good fun. i love it. i think i can guess what we're going on, butjust confirm it. we are going on nemesis. nememis is a classic and is europe's first—ever inverted coaster. it also happens to be shawn's favourite. it's an aggressive start of the day.

shawn, why are you laughing so much? i love it! survived my first ride! it's intense, but it's great. i love it so much. four times, you go upside down on that ride. it's strange to think it was only a short time ago attractions like this fell silent. but this is a place that has a long history of embracing change. before it was a theme park, its main attraction was its gardens. during lockdown, it was an opportunity to get people back out into some fresh air, so we were able to clear some of the pathways that were not necessarily used previously,

and people could come back to alton towers and revisit it as, you know, its intended purpose — a great garden. and for a little bit of escapism, too. of course, yeah, because obviously the earl of shrewsbury wanted to collect all of these elements from around the world. we've got the dutch gardens behind us, the pagoda fountain which was of eastern origin, we've got grecian mixed in with the gothic architecture of the time. well, the gardens have been perfect to change the pace, but with over a0 rides and attractions, i better cross a few more off my list. i've been told there's one ride i simply have to try — it's called the smiler — and it's even collected its own following of superfans that cosplay in the colours of the ride. guys, you look fantastic. thank you. so, tell me about smiler.

when i first saw the ride i was just completely awestruck with it. and from then on it became a big massive obsession. and now i — this is how i dress daily, now. i started a like a group. you started this website, and that's how you all became friends, because you organised meet—ups here. yeah. this is the first time we have met here. yeah, yeah. yeah. oh, really? yeah. this has been a long time coming, then. yeah. so, i'm still not sure if i want to commit to this ride. it is the world's first iii—loop roller—coaster and promises to challenge your body and your mind. meet instagrammer roller coaster rachel and her 10—year—old daughter sappy, who is yet to ride the smiler. but is she finally tall enough? we're hoping she is tall enough. hope so. now i have no excuse.

wish us luck! scary! screaming. after my day here, i can see places like this mean more to people than thrillseekers. i work in health care and elderly care and it was really tough during lockdown and to be able to come back, it was amazing. i class this as a little piece of heaven on earth. if theme parks are your thing,

there is a lot going on this year. chessington world of adventures have new rides. paultons park has a new rides. and legoland has the first theatre flying ride. and if you're heading further afield, disney is celebrating some big anniversaries in paris. and if the last two years have taught us anything, it is the unbridled happiness that escapism can bring. so, my trip to alton towers is done and i think i found a ride that is a bit more me.

naples is a very catholic city. it has religious iconography everywhere and some revere in equal measure, the unofficial patron saint, diego maradona. at a time when naples was suffering from unemployment, poor sanitation and organised crime, maradona, with his own troubled back story, joined the napoli team, giving the neapolitan people something to be proud of. and the owner of this bar claims to have a lock of maradona's hair at the centre of what has become a shrine to the man himself. so this is the famous lock of hair? tell me, where did you get this from?

to end toway, we are back with adventure and you may remember that last year karolis mieliauskas challenged himself to drive this old banger the length of the lake by car and he made a good job of it. this time, he is leaving combustion engines behind him and opted for a cleaner method of transport. wejoin him in sri lanka, where he is about to begin a journey down the historic hamilton canal,

heading for the capital, colombo. along the way, he will discover how pollution has taken its toll and how locals are doing their bit to clean it up. long time no see, sri lanka! so humid already. hello, gentlemen. i'm looking for a traditional boat to rent for maybe four days or five days. i want to go down the canal. 0k, can you give me a street number? house numberfour, if i understand right. i was following the track and someone told me to go right and then left and here i am.

a small catamaran is here. adventure is the very first step and the trip starts. i hope to do it in three days. ok, the first 100 metres is done! as i start myjourney i get a warm welcome from the people who live here. hello, hello, how are you? shouting from banks. good? very good! very good. i'm going down the canal. goodbye! see you, all the best. and what does the sign say?

"dear neighbours, keep the canal clean." no good. i was expecting to see some rubbish but not that bad. not that bad. looks like the rubbish comes from these houses. tell me please, is that right, you are cleaning the tunnel? how many people like you are they here? six people who are cleaning? i think i can see one now, approaching, hello. that is nice. that somebody is doing this. there is also a local boat company that collects rubbish on their days off, run by a man called fernando.

0ur cleaning project is called captain fernando cleaning project and we started this in 2016, actually five years ago, so step—by—step, we came to a very good stage. plastic pollution is a big problem these days. if you walk on these speech, it is very polluted and if you go now, the canal and lagoon is very polluted. -- if —— if you walk on this beach. now people are slowly, slowly changing. people throw the rubbish into the canals but now people starting to think, little by little. so a long time ago, those canals were used for transportation but these days, people are using them to dump rubbish. the easiest thing is not to throw rubbish into the canal and what we can do is educate your

brothers and sisters so we can have a clean and healthy lifestyle. so, boys, thank you for coming, if you are not using plastic so we can make a better life for all. thank you. let's make some noise! thank you, fernando! thank you, karolis. looks like fernando is doing a great job and i'm happy to see that someone like fernando is working on these issues, to make our world much greener. and now, i'm approaching where i'm getting off. coming up next week, more from karolis as he continues his journey down the canals in sri lanka. and how a busy re—wilding project is bringing life back to some of the biggest national parks.

it's a female deer and i can see her in the distance, camouflaged and i can't believe we found one. in the mean time, check us out on social media at bbc travel show. and we are also on the bbc iplayer with loads more fun from our recent trips. in the meantime, enjoy your travels and i will see you very soon. hello there. it looks like the weather is going to cool down a bit from tomorrow, but today most parts of the country will again be warm with some sunshine.

but we've got this change happening, really, across some western most parts of the uk, with those weather fronts actually bringing more cloud and bringing some rain as well. but ahead of that, with the sunshine, pollen levels are remaining high across much of england and wales, but also into some central and southern parts of scotland, where we're seeing the best of the hazy sunshine. there is a bit more cloud across southern parts of scotland, that rain mainly affecting the western isles this afternoon, continuing in northern ireland and some rain pushing late in the day into western fringes of wales and the far southwest of england. that will peg the temperatures back a bit here, but ahead of that in the sunshine, temperatures are widely 18 degrees and could make 20 for the fa cup semifinal at wembley. that band of rain then continues to push its way eastwards overnight. it'll be followed by some showers for northern ireland into scotland and over the irish sea, and the breeze will pick up a little bit as well. temperatures overnight will be at sixes and sevens, but as you can see, there's little or no rain running through the midlands,

much of southern england as well, that weather for much weaker here. it's more active further north, and that's where we've got most of the rain nearer that area of low pressure. and it's around that that we've got the stronger winds overnight and into tomorrow. the winds more of a westerly and that will bring in cooler, fresher air. there's our weather front, that band of cloud there. the rain moves away into the north sea. cloud could linger in the southeast, perhaps, for a while, and then we'll see some sunny spells, a few showers around, most of the showers for northern ireland and particularly western scotland, where we've got these stronger winds for all of us. it will be cooler during tomorrow, but still 16 or 17 degrees with some sunshine towards south eastern parts of england. heading into tuesday, it probably starts off quite chilly. actually, those showers of monday will have cleared away and then we'll see more showers developing, i think, on tuesday. slow—moving, perhaps heavy, showers, some sunshine around as well, but temperatures are continuing to drop away. typically, 13 or 1a celsius in the afternoon and really through the rest of the week, it remains dry, those showers do tend to fade away,

but we'll see easterly winds picking up. that means temperatures are going to be near average and the best of the weather is likely to be in the west.
