“Wat Si Chum Sukhothai is a temple that enshrines Phra Achana. which is a Buddha image in the posture of Mara”
This lies about 1,500 meters north of Wat Mahathat and was originally surrounded by a moat. A square mondop which is the main sanctuary, contains a monumental stucco-over-brick Buddha image in the attitude of Subduing Mara called 'Phra Achana.' which is 11.30 meters width_.
The mondop is 32 meters square and 15 meters high, and the walls are 3 metres thick. There is a passageway in the left inner wall itself which leads to the above crossbeam. On the ceiling of the passageway are more than fifty engraved slate slabs illustrating Jataka scenes.
