On the beaches, we found something secret hidden beneath the sands. I'm meeting eddi pitcher, a writer and travel journalist who specialises in uncovering hidden places. Eddi, where are you taking me today? so we are taking the wild way to bolonia beach, and we can see that this is the way because we've got. . . Knotted beach grass here. There are no signs. So it's. . . I said it was a wild way. I'm definitely glad that eddi's here to show me the way on this one. Wow, look at this. There you go. So you've got your desert dune there. Wow! this is the bolonia sand dune, one of spain's largest sand dunes, standing at over 30m high and 200m wide, all concealed within the estrecho nature park. Probably the best way to think about this coastline, which is endlessly shifting down the centuries, is as a living sand dune. And now, with climate change, the winds are getting stronger and pushing with them these dunes. So they're really moving? yeah, exactly. These dunes are being battered by hurricane force winds, forcing them inland and revealing some remarkable hidden history concealed below. If you think about it in terms of history, this is a melting pot of cultures. You've got africa, you've got europe, you've got all of the mediterranean, and then the travels across the atlantic. And all of those peoples have left their vestiges, their archaeological sites, along this coastline, which have been kept perfectly intact down the millennia. My next stop is cape trafalgar, 60km down the coast from bolonia, where archaeologists from the university of cadiz have just discovered some remarkable ruins, thanks to these moving sands. So when you discovered and realised it was a tomb, you must have been preparing to find some bones in here, right? so excavate here is very similar to the excavation in egypt tombs. And the sand preserve very well the bones. So the state of preservation of the tomb of the bones, the grave goods, is excellent. We have an arrowhead. Tiene cuatro mil anos de antiguedad. Pendant. I can't believe i'm holding in my hand a piece ofjewellery from thousands of years ago. That is amazing. Por ultimo. . . A bead? and these aren't the last of the mysteries which this magnificent coastline is concealing. Finding two neolithic tombs is extraordinary enough, but this coast has even more buried treasures. In fact, looking around, i can see people lying on their beach towels, probably not knowing that beneath them could be a whole ancient roman settlement. If you are on the beach and you have an umbrella and you leave your umbrella on the beach in a windy area, after some hours, it will be completely covered by the sand. And this is what has happened here. So, what can you tell me about this site? what are these walls? this is the roof, more or less, of the roman baths. Wow. So it's much deeper? so how deep do we have to go down? four metres down. Four metres? but could we have a go at maybe exposing just a bit of it to see more of what's down there? yes, yes, of course. Thank you very much. All right! four metres is a long way down. Yeah! this is going to take me probably more than the afternoon, i'd say. Yeah. I think i'm going to have to accept defeat here. Besides, the archaeologists have purposefully decided to cover up this site with sand in order to protect it from the elements — a decision which might prove difficult in the long—term, thanks to those strong winds and shifting sands. Some history worth thinking about next time you're stretched out on a spanish beach. Right, from the south, let's head to the other extreme now. The town of san sebastian is pretty much as far north as you can get in spain. It's in the basque country, a region with a culture and traditions all its own. San sebastian's earned itself quite a reputation as a foodie capital. So why, then, were some bars and restaurants there charging tourists over the odds for a regional speciality? we gave lucky lucy the enviable task of finding out. This northern spanish city holds one of the highest number of michelin stars per square metre in the world, and they also claim to have the most bars per person. So this place sounds right up my street. And the basques have their own way of eating, too. It's all about pintxos. My guide to the pintxos scene is luis. He grew up in san sebastian and he runs pintxo food tours. Hi. So this is my first time trying pintxos. How does it all work? well, pintxos is our tradition. It's the way of socialise and meet friends, changing very quick from one bar to another. 0ne bar, one drink, one pintxo. Let me show you inside the. . . All right!. . The varieties that we have. So i can see a lot of food. It all looks really good, but what's going on? well, it's not easy because there are a lot of possibilities. 0n the counter, we have the fresh pintxos. And if you follow the blackboard, we have the warm food, the warm pintxos that come directly from the kitchen. And this is all made today, daily. . . Very, very fresh. . . Made throughout the day. And maybe in 20 minutes or half an hour, they need to, you know, renew the pintxos that you can see on the counter, because always is full of people and it's very, very fresh. As a tourist who comes to san sebastian, they're not really sure how pintxos works, explain to me what is. . . What are the rules? 0k, first, go where the locals go. Mm—hm. Second rule is one bar, one drink, one pintxo. And the third rule — asks the waiter for the speciality. Because every week change, every season change the pintxos. It's very interesting if you ask the waiter which is the speciality, the speciality today. But recently an undercover investigation by a local journalist caught some pintxo bars double pricing. Two tourists went out and ordered the exact same dishes as two locals who ordered in the basque language. Over the night, the tourists paid about nine euros more. The experiment was conducted twice in the same month at seven of the old town's pintxo bars. So let's talk about that investigation. You know, we've got to talk about it. How did the locals react to that? yeah, i think it's interesting to have this information because we can. . . The locals, we can boycott these bars that make a different price for locals and tourists, no? for us, it's very important to give the best service. . . Yeah, of course. . . Not only for locals, also for travellers from all over the world. Most of the pintxo bars are in the old town. In fact, there are more than 200 to pick from, which can be a little overwhelming, but it all becomes clear when you have someone to explain how it works. Ok, so talk to me about pricing, because i can see prices on the board here, but there's no prices here. So how does it all work? yeah. The pintxos that you can see on the counter, you can take by yourself directly without waiting the waiter. And you can take one, two or three, whenever you want. And before leaving, you can say to the waiter how many pintxos have you eaten and pay for that. Yeah. So people can come in. They don't need to wait to be served. They can take the food. And then based on this trust system, you pay for what you've eaten and drank and then you leave. Yeah. Because normally the people is very honest because it's not normal in other big cities especially. No, i've never come across a system like this before. Yeah. It's very trustworthy. Yeah. And also it's easy for the waiters because price normally is the same for all the variety of pintxos, and you say three. . . Yeah. . . Is. . . Three euro for three is nine euro, you know? pintxos isn't all about the old town and tradition. Luis takes me to meet a chef who's putting a modern twist on it all. Hi. Hola! so are you from san sebastian? do you live here? what's the secret to good pintxos? gracias. All in one? yes. 0k. Before i leave, luis took me to one of his favourite places and has one more thing in store. Just for finishing the tour. . . Mm—hm. . . I have a surprise for you. A surprise, huh? i like surprises. This is a temple for t—bone steak lovers, but we will try cider. Hola! san sebastian is full of cider houses, some of them more than 500 years old. Takes a certain amount of skill to pour like that. Why do we do that? because we love to drink the cider with the bubbles. 0k? i'm all about the bubbles. 0k. Both: topa! wow. That's very fresh. Very fresh. Now, one of malaga's biggest attractions also happens to be one of the world's most famous artists. I wonder if you can guess who it is. The atmosphere of everyday life in the city was said to have inspired him, but his personal life was tumultuous and he left a complex and troubled legacy. Well, last year marked the 50th anniversary of his death, so we sent rajan to the city to better understand the life and work of pablo picasso. Rajan: born here in 1881, picasso actually only lived in malaga until he was ten. But 50 years on from his death, the city is making the most of its illustrious local boy. There's postcards, fridge magnets, bags, and even language courses. Picasso's influence is everywhere. But the main event is the museo picasso malaga. Founded 20 years ago, it has over 300 works from across his life, housed in what was previously a 15th—century palace. Picasso's works are now some of the most valuable in the world, with paintings like this one sold at sotheby�*s in 2018 for around $69 million. Many of the paintings and sculptures in the gallery were donated by his children at picasso's request. Three different visions of doves, yeah. Doves were used by picasso as symbols of peace, and his image of a dove would be adopted as an emblem of world harmony. He lived through some of the most turbulent events in modern history, including the spanish civil war and two world wars. These would be a profound influence on his work, perhaps most famously illustrated in guernica, a dramatic painting depicting the horror of the bombing of the spanish town by fascist forces during the civil war in the 1930s. And ten minutes' walk from his birthplace is an arena that arguably influenced picasso the most — the malaga bullring. He would come here with his father every weekend, and it would inspire his first known artwork, aged eight, an oil painting on wood which captures the colour of the bullfight. What the bull represents in picasso's work is widely debated by critics, some saying it stands for power and masculinity, others cruelty, brutality and suffering. Today, bullfighting still goes on in malaga, although it's widely criticised by many people, both here and abroad, for its cruelty, with increasing calls for it to be banned. But there's no doubt the bull was an enduring legacy of southern spain throughout picasso's artistic career, no matter how controversial it's now become. At points, while being in malaga, it feels like the whole city has been an inspiration to picasso — even the sunsets. El pimpi is one of the most famous wine bars in malaga, and it revels in the great artist's legacy. This room is called the picasso room. Did picasso ever come here? no. No! despite this, er, minor detail, it hasn't stopped the bar from capitalising on picasso's brand. Wow. So, in 2003, in april, she came here? and maybe the myths, legends and vague associations are becoming as much part of picasso's appeal as the real facts. Christa: finally, this week, one of my favourite memories from spain — and this time, back on the southern coast, on the blustery little strip of land just 14km north of the tip of the african continent. Actually, tarifa is known as the windiest spot in the whole of europe. And as a result, it's become a favourite for windsurfers and kite surfers from everywhere. So i went along to find out why some see this sport as a breath of fresh air. We'll see you again next week, but until then, sit back and enjoy with me the acrobatic twists and turns of the annual kitesurfing world championships in tarifa. The winds here can reach up to 60 knots, with the athletes expertly manipulating it to fly over 30 metres high. I've headed over to the leaderboard to see how the competition is shaping up. So, the best of the best kite surfers in the world are competing here today. That's 60 competitors, but they are divided in five divisions. We've got 2a men and we got 12 women. It's an elimination system, so they are riding in groups of two or three riders at the same time, and then the winner advances to the next round. But we'll see at the end of the day who's going to arrive at the final and who's going to take the crown. There's a reason why the wind is so consistently good here in tarifa. Judge and commentator lewis explains why. Here is so special. Because it's so close to the north of africa, what happens with the geology of the land is these mountains push up and then you get this strong wind that comes in. You've got to think of an hourglass where the sand rushes through the middle. That's what happens here in both directions, either from the atlantic or the mediterranean. That is why it's so uniquely always windy and so strong. I think we're going to see something very special later. Now that the winds are getting stronger and the competition is really heating up, i want to know how the athletes are doing. Lorenzo, congratulations. Thank you a lot. Looked incredible out there. What's it like out there? the wind is pumping. It's 30 knots and we're flying really high. It's just an unreal feeling. When i'm doing my best tricks, ijust feel like superman on the water. It's like i've got a superpower. It's great. It's great energy on the beach. The wind is super strong, and that's exactly what we're looking for. So, hopefully i continue to make it and arrive i in the final soon. Well, congratulations and good luck for the next stage. And yet the medieval town of tarifa and its surrounding beaches were not always home to this global influx of tourism. Tarifa is a really bustling town, and that certainly wasn't always the case. In fact, very few tourists came here, because why would you want to sit on the beach with such a wind blowing all the time? but then in the 1980s, the world came to love tarifa's wind and everything changed. Tell me about the first time you came to tarifa. Well, i came through this entrance with my car, full of boards, and then we get stuck in one of these small streets. In yourcar? yeah, in the car. Stuck in a tiny street. It is absolutely tiny. Yeah. I've come to the old town to meet michel, who in 1982 left his hometown and chased the wind, to wind up in tarifa, opening the town's first—ever kite surfing school. Why were you coming to tarifa? well, i camejust searching the wind. It was a paradise for windsurfing. Wind every day. Long beach, sandy beach. Nobody. That's perfect for us. In fact, before kite surfing came to tarifa, there was an exodus of locals leaving the town to find work. Now, locals can stay in their home town thanks to the employment opportunities which this sport has brought with it. So, at the end, we are the ones who push this town up. You did a good job. Yeah, we did a good job. Sometimes you think it's better not to do it because then we have a perfect spot for us. Right now, it's full of people. . . You gave the game away. Yeah, but. . . Now everyone knows. Always, when you think that one, it's too late, so that's the problem. I've met with tanja, owner of one of the a0 — yes, that's a0 — kite surfing schools that line this coast. It's time to experience what this legendary wind feels like for myself. 0h! that's great. 0h! but, you see, once we're in the water, you see that it will feel quite natural. I wouldn't bet on it, tanja. Hello. This weekend will take us out of august and into september — technically speaking, the start of the meteorological autumn. But in spite of that, there is some warmth and some humidity on the way. Warm and humid conditions drove a lot of the showers and thunderstorms across the western side of continental europe during friday. That warm and humid air wafting its way northwards over the weekend. And while there will be some spells of sunshine, we also have the chance of some pretty intense thunderstorms, although there is still a lot of uncertainty about exactly how many of those there will be and where they might crop up. And actually, saturday will be a largely dry day. Quite a lot of sunshine around, more cloud spilling into southern parts of england, perhaps south wales, and the chance of one or two showers and perhaps the odd thunderstorm across the channel islands and perhaps south—east england later in the day. A breeze will keep things cool close to these north sea coasts — 17 for aberdeen and newcastle. More generally, though, 19 to 22 or 23 degrees, so quite a warm day. Quite warm and humid overnight, through saturday night into sunday, especially across the south, and we will see further, very well—scattered showers and thunderstorms pushing northwards, i think especially across some eastern counties of england. 16 degrees the overnight low in london, a cooler 9 degrees there for glasgow. As we go through sunday, well, that warm, humid air continues to push northwards. With it, quite a lot of cloud and the chance for one or two of those showers and thunderstorms. If they do crop up, they could bring a lot of rain, perhaps some squally winds, maybe some hail thrown in, especially across eastern england, but many spots will avoid the showers and stay dry. 19 to maybe 27 or 28 degrees down towards the south—east. Now, through sunday night, we will see further showers and thunderstorms, perhaps most especially across eastern england. But low pressure�*s swirling in from the west, and that means from monday, there will be a lot of cloud, there will be some outbreaks of rain. Some of that rain will be heavy, possibly thundery. It could really be quite misty and murky around some coasts out towards the west, but we will see some spells of sunshine as well. Still getting up to around 25 degrees across parts of east anglia, but out towards the west, things will be turning cooler and fresher. And that sets the theme, really, through the middle part of the week — some cooler conditions, some rain at times. It might warm up again, though, for some of us by the end of the week. Among those killed was a 14—year—old girl on a playground. The six others were killed when the strike hit an apartment buiding. Many others were wounded, including 20 who are in a severe condition according to the regional governor. Ukrainian officials said the area was hit by a guided bomb. Kharkiv has come under heavy russian attacks for months. 0ur correspondent abdujalil abdurasulov has the latest. The city of kharkiv is located 30 kilometres from the russian border so moscow targets the city on a regular basis using bombs, using drones and guided bombs, using drones and guided bombs as well and for many people in kharkiv their life is russian roulette. Each day you can only guess who and what moscow will target next. Today, russian bombs killed people in an apartment block. They also killed a 14—year—old girl in a playground. The guided bombs
