Temples that we can see in Thailand are distinguished by their unique architecture. Slender, triangular, hipped roofs that are often decorated with images of a mythical snake. A structure in which relics and books are kept is called a stupa or chaitya and usually has a bell shape. The place of worship, which consists of a larger complex of buildings, is commonly referred to as a wat. Within the complex there may also be a school, a place of assembly and monastery. Traditionally, temple complexes should be surrounded by two rings of walls.
