About 200m from the Pratu Chiang Saen (the historic main gateway to the town’s western flank) are the remains of Wat Pa Sak, where the ruins of seven monuments are visible in a historical park. The main mid-14th-century chedi combines elements of the Hariphunchai and Sukhothai styles with a possible Bagan influence, and still holds a great deal of attractive stucco relief work.
