If there are a few world heritages to go in the world, Angkor City is one of them. It is a huge and mysterious ancient capital that is known for being the last capital of the Khmer Empire. It is surrounded by pastor houses, civil and military officials, and the government hall. These buildings were built of wood and have been corroded, but the remains of the stone buildings confirm that the Angkor Thom is as great a city as its name suggests. The entire city of Tongwang is square shaped, with a perimeter of 14 kilometres and a moat that is 100 meters wide. There are 5 gates in the city, and there are four-faced Buddha statues on the top. There is also a bridge across the moat. The south gate and the north gate are the daily passages of the people. The east gate is used for funeral. The west gate is for the criminals.
