The princely city of Sri Satchanalai, a former satellite city from ancient Sukhothai located near the Yom River, was founded in 1250 and in the 13th and 14th centuries served as a residence for the crown prince.

Today this Historical Park features several ancient ruins, such as those of Wat Chang Lom (fig.) and Wat Chedi Jed Thaew (fig.), as well as this hilltop temple Wat Khao Phanom Phleung, which lies at the end of a steep laterite staircase.
