Si Satchanalai Historical Park

The Si Satchanalai Historical Park is a historical park in Si Satchanalai district, Sukhothai Province, northern Thailand. The park covers the ruins of Si Satchanalai and Chaliang. Si Satchanalai, which literally means "City of good people", was founded in 1250 as the second center of the Sukhothai Kingdom and as a residence of the crown prince in the 13th and 14th centuries.

The city was rectangular in shape. In the 16th century, a 5-metre high wall with an upstream moat was built to fend off the growing Burmese attacks. The location of the town was facilitated by two neighboring dominant hills.
