Wat Lokayasutha is situated in the West of Ayutthaya. There is no historical record of its background. The temple buildings are aligned along an east/west axis. There are three wihans lined up in front of the main stupa. At the back of the stupa there is the Ubosot and Viharn of the Reclining Buddha.
The Reclining Buddha of Wat Lokayasutha is decorated in regal attire. His head is at the north end and his face is turned to face east. In 1954, the Reclining Buddha was restored by coating the whole sculpture and changing the Buddha’s head to a regal attire style.
