Outside of Si Satchanalai’s town walls is the Wat Phra Si Rattana Mahathat, one of the oldest temples of Si Satchanalai Historical Park. The large temple is located East of the historic walled town in Chaliang, on a small peninsula almost entirely surrounded by the Yom river.
The Wat Phra Si Rattana Mahathat predates the Sukhothai era. It was founded in 1237, when the area was under control of the Khmer empire from Angkor. It was restored and expanded during the Sukhothai and Ayutthaya eras.
Today, the temple is an active monastery with a modern ubosot and kuti, the monks living quarters.
