Sri Thep
Si Thep was an ancient city in the Pa Sak valley, enclosed by moats and divided into an inner and an outer town. Its monuments and sculptures show the meeting of local traditions with Hinduism and Buddhism in the Dvaravati world. Beyond the town stood Khao Klang Nok, a great stepped monument of laterite, while the nearby cave of Khao Thamorrat housed Mahayana Buddhist sculpture. Later Khmer-style towers added another layer to a sacred landscape that had flourished long before the rise of Sukhothai.
