The Historic Town of Sukhothai and Associated Historic Towns is a Unesco World Heritage site which consists of Sukhothai historical park, Kamphaeng Phet historical park and Sri Satchanalai historical park. These historical parks preserve the remains of the three main cities of the Sukhothai Kingdom which had flourished during the 13th and 14th century CE. The Sukhothai Kingdom is viewed as having been the first of the Thai kingdoms.
The Sukhothai Historical Park (Thai: อุทยานประวัติศาสตร์สุโขทัย) covers the ruins of Sukhothai, capital of the Sukhothai kingdom in the 13th and 14th centuries, in what is now the north of Thailand. It is located near the modern city of Sukhothai, capital of the province with the same name.
