Wat Sa Si, Buddhist temple ruins in Mueang Kao, Thailand
Wat Sa Si is a temple complex set on an artificial island within Traphang-Trakuan lake, featuring a central stupa built in a Lankan-influenced style. Smaller stupas are scattered around the main structure across the surrounding water.
Built in the 14th century during the Sukhothai Kingdom, this site served as a religious and educational center for local people. It reflects a period when temple construction reached a high point in northern Thailand.
The temple layout reflects how Buddhist faith shaped the design choices of medieval builders in this region. The way the structure sits in water shows a spiritual relationship with nature that remains visible today.
Entry is through the Sukhothai Historical Park entrance, where bicycles can be rented for getting around. A bike allows you to visit this site and other ruins in the park at your own pace.
The main stupa stands on its own artificial island and creates mirror-like reflections in the water at sunrise and sunset. These visual effects shift based on the season and water level changes.
