This is a study of the development of Art and Architecture in Thailand with Buddhism. The Culture of Thailand has two important sources of origin: indigenous and foreign. The indigenous source comes directly from the ideas and inspiration of the people while the foreign sources came through its cultural contact with other great civilised nations such as India and China. In the field of art, it mainly deals with religions such as Buddhism and the cultural and artistic relationship with India, and other countries. Thai art served religion, which formed the national ideal and conception of life.
