The Burj Khalifa located in Dubai, United Arab Emirates is the worlds tallest building. Seeing this building in person was extremely impressive, all i could think about is how humans made something this huge. You can see this building from almost anywhere in Dubai. i almost went to the top but it was $100 so i decided to not do it. At the base there is a huge water fountain that puts on shows all the time. The architect who designed this building was Adrian smith.
