In 1362, King Maha Thammaracha I (Li Thai) of Sukhothai moved his capital to Phitsanulok, where he built the Chan Palace on a mound on the west side of the Nan River, which is presumed to have been the residence of the Thai monarch from the Sukhothai period to the Ayutthaya period.

When King Borommatrailokanat of Ayutthaya moved the capital to Phitsanulok in 1463, his highness used the palace as a royal residence.

While construction workers were digging holes for foundations, they discovered the old brick remains of the palace, which then the Fine Arts Department registered as a historic site.

On 26 November 1993, with an area of 128 rai, 2 ngan, 50 square wah, according to the letter from the Ministry of Education, 07/4954, ordered the Fine Arts Department to designate the palace as a historical monument.

In 2005, Phitsanulok Pittayakhom School moved from Chan Palace to Kaeng Yai Area until it was completed.
