Originally built in the old village of the valley, now sunk when the water of the large lake submerged it.
Also known as Wat Saam Prasob, the sunken temple was built in 1950, but it sunk in 1968 when the water of the lake submerged it. Later when the bridge and dam was constructed to prevent overflow of water, the only thing left of the temple to see was the upper section of bell tower. However, if you visit here towards the end of dry season, you can get a chance to walk around the ruins a little. To get to this place, the locals offer boat rides across the lake.
