The Burj Khalifa is an incredible tower in Dubai. It’s approximately 828 metres tall. That’s almost twice the size of the Empire State Building! There are 900 homes in the building, plus offices, hotels, restaurants and sports centres. There’s a big lake next the tower. They have spectacular shows with fountains and music there. For people who like relaxing in the water, there are a number of swimming pools, including an outdoor pool the 76th floor. And for people who love shopping, there’s an enormous shopping centre the Burj Khalifa. But there is one problem with the Burj Khalifa. Some days, when you look down, you don’t see a thing! That’s because the top part of the tower is sometimes the clouds and you can’t see what’s them!
