Have killed almost a50 fifty people. More than 60 are still missing. Now on bbc news, Lucy Hedges Heads to the city of naples to see how staff at pompeii are using four legged robots and drones fitted with lasers to uncover what life was like in this ancient city. This week on the show. I head underground in naples to get a Sneak Preview of an amazing archaeological discovery. Oh, my gosh look at this plus, Find Out Why A Certain World Famous Footballer has a shrine dedicated to him in the city. As restrictions are rolled back, cat is on the road in the uk to take a rollercoaster recovery ride. And were heading to sri lanka to find out about a Cleanup Campaign along one of the countrys historic canals. This is one of the most archaeologically significant 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 its come a long way since then, partly thanks to a new director, whos 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 isjust continuing. And how do you think this will change the perception of how pompeii used to be . Its really about the vision of the past. Its not only the big families, not only the senators and the ones who got the statues in the forum, and the local authorities, but its also the slaves and women, who often 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, thats 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 a legged robot that, bizarrely, looks like a dog. Good dog. So, paolo, ive got to be honest im geeking out over this. This has got to be the coolest, most elaborate robot i have seen in my life. But tell me about what im staring at. There is a lot going on here. Its 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 thats 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. Its an archaeological gem thats even older than pompeii, but up till now has been hidden from public view, beneath a private home, and ive been lucky enough to have a Sneak Preview before the site fully opens to the public later this year. But first, im meeting meeting the woman who spent years persuading her husband to share this unique family treasure. During this 26 years, i dont know how many people ask him to open it. But not only kings or prince or archaeologist, or isabella rossellini, i dont know how many people. So i say maybe we have to open it. And he say no, no, no please alessandra, dont 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. Oh, my gosh. Yes. Look at this. This is the start. The detail its full. So youve 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 still 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 was bad. Yeah. And if you go over there you can see that the shes full of colour, and you can see the teeth and this incredible and its really unique. And shes the start. It is amazing to think that these terms laid undiscovered for over 2000 years. But thanks to alessandras powers of persuasion and a lot of hard work, from thisjune, theyll be open for everyone to see here in naples. Right, back to the uk, next. Weve been busy touring some of the countrys 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 rollercoaster. As restrictions relax, im travelling across the uk to see how ready the countrys top attractions are, to meet the people getting us excited about travel again, and hear their plans for the new normal. Todays trip is to staffordshire. And to reach the gates of my chosen attraction, im taking the monorail. Hello from alton towers, the largest theme park in the uk. Now, itsjust opened for the season without any Government Restrictions in place. And although its been around for over a0 years, i have a confession to make this is my first time here. So lets go. Sprawling over 900 acres, this was once the residence of the earls of shrewsbury. And being a themepark novice, ive enlisted some help. Were about to do the three rides that theyve got up on the stratosphere. Shawn sanbrooke is a full time Rollercoaster Vlogger with a lot of followers. No worries. Shawn, are you a celebrity . I wouldnt say that. I love sharing my adventures. But its all good fun. I love it. I think can guess what were going on, butjust confirm it. We are going on nemesis. Nememis is a classic and is europes first ever inverted coaster. It also happens to be shawns favourite. Its an aggressive start of the day. Shawn, why are you laughing so much . I love it screams of delight. Survived my first ride its intense, but its great. I love it so much. Four times, you go upside down on that ride. Its 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 themepark, 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. Weve got the Dutch Gardens behind us, the Pagoda Fountain which was of eastern origin, weve 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. Ive been told theres one ride i simply have to try its called the smiler and its 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 like a group. You started this website, and thats 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 im still not sure if i want to commit to this ride. It is the worlds First Ia Loop Rollercoaster 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 . Were hoping she is tall enough. Hope so. Well, now i have no excuse. Wish us luck this is scary screaming after my day here, i can see places like this mean more to people than thrillseeking alone. I work in healthcare and elderly care and it was really tough during lockdown and to be able to come back, it was amazing. I class this as my little piece of heaven on earth. If theme parks are your thing, there is a lot going on this year. Chessington world of adventures are hosting a mardi gras event with a difference this may. Paultons park have a brand new Junior Coaster called the farmyard flyer, and Legoland Windsor has the uks first flying theatre ride called the flight of the sky lion. And if youre heading further afield, disney is celebrating some big anniversaries at its parks in florida and paris. And if the last two years have taught us anything, its the unbridled happiness that escapism can bring. So, my trip to alton towers is done, and i think ive found a ride thats a bit more me. Naples is a very catholic city with religious iconography everywhere, but some revere in equal measure the citys unofficial patron saint, Argentine Footballer 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 local team and gave neapolitan people something to be proud of. And the owner of this bar claims to have a lock of maradonas actual hair at the centre of what has become a shrine to the man himself. So, this is the famous lock of hair. Tell me, bruno, where did you get this from . To end this week, were back with adventurer karolis mieliauskas. You might remember that last year he challenged himself to drive this old banger the length of lake baikal, and made a pretty good job of it. Well, this time hes leaving Combustion Engines behind him and opted for a Cleaner Method of transport. Wejoin him in sri lanka, where hes about to begin a journey down the historic hamilton canal, heading for the capital colombo. Along the way, hell be discovering how pollution has taken its toll and what locals are doing to clean up their waterways. Long time, no see, sri lanka.

So, step by step, we became to a very good stage. Plastic pollution is a big problem these days. If you walk on this beach its very polluted and if you go on our canal, a lagoon is very polluted. Now, peoples minds are slowly, slowly changing. People just throw the rubbish into the canals, but now people start to think, little by little. So, a long time ago, those canals used for transportation, but now, these days, people use that to dump rubbish. The easiest thing is not to throw rubbish into the canal. What we can do, educate your brothers and sisters so we can have a clean and healthy lifestyle. So, boys, thank you very much for coming. If you are not using plastics, youll help out for the good of all. Thank you. Yeah, lets make some noise. Cheering thank you, fernando. Thank you, boys.

Youll find us on facebook and instagram at bbc travel show. And we are on the iplayer, too. Until then, enjoy your travels and i will see you very soon. Bye bye. Hello, there. 0n good friday and into the easter weekend, we saw temperatures reach the Low 20s Celsius in the warmest places, but weve lost those values now. Today is a cooler day, not particularly cold, but certainly cooler than what weve had over the last few days. Weve got a bit more cloud around with a few showers, too. Its all because weve got this area of low pressure influencing our weather throughout the day and again into tomorrow. Its bringing stronger winds, especially to the northwest of the country. Its introduced this cooler air, as you can see from the blue hue here on the air mass chart. So, a chillierfeel to things across northern and Western Areas through the afternoon, particularly where we have the stronger winds low teens here. But we could still make 16 or 17 degrees in the southeast given some sunshine. But there will be one or two showers dotted around and those may last into the evening period across england and wales. Variable cloud, clear spells here. Clear skies for scotland and northern ireland, but some cloud across the far northwest, so it wont be quite as cold here as what it will be where we have the clearer skies. So, A Touch Of Frost in one or two spots across the north and the west. A chilly start to tuesday once again. Maybe A Touch Of Frost across parts of scotland and northern ireland. This Weather Front across the northwest of scotland, bringing outbreaks of showery rain. The winds will ease down through the day. England and wales will start with sunny spells, a bit of cloud and then into the afternoon could see a few showers developing, and there could be the odd heavy one in places. Theyll be slow moving because the winds will be much lighter. A cooler day across the board, 13 to 15 degrees will be the afternoon highs. Into wednesday, were in between weather systems, a ridge of High Pressure exerting its force across the country. So, a largely quiet day, i think, mainly dry for most of us. Variable clouds, some good spells of sunshine around. There will be a noticeable easterly breeze developing across eastern england, so that may make it feel a bit cooler here. But further west, we could see highs reaching 17 or 18 degrees, given some sunny spells. And a drier day for the north west of scotland. Towards the end of the week this area of low pressure out west dives southwards to the south west of the uk. It doesnt look like its going to affect us through thursday and friday. This area of High Pressure to the north of the uk will be dominating the weather scene, bringing us fairly brisk easterly winds. So, i think through thursday, increasingly into friday, itll start to turn chilly along some north sea coasts. Probably the better, drier, brighter, warmer weather will tend to be further south and west. This is bbc news. Welcome if youre watching here in the uk or around the globe. Im lucy hockings.
