This is a serial property of three component parts: a distinctive twin-town site, featuring an Inner and Outer Town surrounded by moats; the massive Khao Klang Nok ancient monument; and the Khao Thamorrat Cave ancient monument. Together these sites represent the architecture, artistic traditions and religious diversity of the Dvaravati Empire that thrived in Central Thailand from the 6th to the 10th centuries, demonstrating the influences from India. The local adaptation of these traditions resulted in a distinctive artistic tradition known as the Si Thep School of Art which later influenced other civilizations in Southeast Asia.
