This is a group of towers. It is a national monument to the independence of Bali (from the colonial rule of the Netherlands). It was built about a hundred years ago, so it's well preserved. Indonesia also has a "Borobudu" which is located in Java Island, Indonesia. It and China's Great Wall, Egyptian Pyramid, Angkor Wat in Cambodia, Taj Mahal in India are known as the five miracles of the ancient East. There is only one "small" difference between the two names, but it has nothing to do with them. So don't get it wrong.
