The Sukhothai period is renowned for its stylization of the Buddha's features, which are portrayed as slightly feminine with a fuller, rounder face and a flame situated above the head. The fullness of the face was probably introduced to reflect the prosperity of the Kingdom at that time. There are many awe-inspiring Buddha images hidden throughout every corner of the park.
Along with the ruins of the ancient royal palaces there is a monument to King Ramkhamhaeng, who reigned during the pinnacle of the Sukhothai period. King Ramkhamhaeng is known as the father of the Siamese language (Thai), and the monument's stone inscriptions detail the development of the Thai alphabet.
