In the heart of the city Julia Bland, an architecture student, talks about public squares. Big cities are busy, crowded and full of traffic. City people like to go to parks. Even though they’re still in the city, it feels like they’re far away from the traffic and chaos. But there are also public squares where they can relax. Squares aren’t green spaces. In fact, they’re the opposite because they’re usually surrounded by shops and cafés. However, they’re very important because they’re social spaces. People go there to meet their friends, have a coffee or a meal, maybe to shop at an open market or see a concert. A few years ago, I visited China and while I was there I went to Xinghai Square in the city of Dalian. I couldn’t believe the size of the square – it’s 1,760,000 square metres, which is about the size of 243 Wembley football fields! In fact, it’s the largest square in the world. Most people in Dalian live in tall buildings and they really need a place where they can be outside and enjoy themselves. The square is by the sea and there are amusement parks, shopping malls and museums. It took me hours to walk all the way along it, but it was a cool experience! Public spaces have been around for thousands of years. The ancient Greeks called theirs the ‘Agora’. It was an open area in the most central part of the city where people bought food, did business and discussed politics. The Romans called their public space the ‘Forum’ and it had shops, markets and theatres. The ancient sites in Athens and Rome still exist, though, these days, they’re full of tourists, not shoppers and shopkeepers! But if you go there, you can get an idea of how the ancients lived. Even villages have a public area where the local people can meet. It might be a small square or an actual grassy area that is known as the ‘village green’ in the UK. Hundreds of years ago, people took their animals to eat the grass on the green. It was also used to celebrate important events such as May Day – in many places, it still is. If you’re ever in the UK, don’t miss the opportunity to visit one of these beautiful little villages. You’ll be really glad you did! Câu hỏi 1.
