“Wat Sai”, formerly known as “Wat Soar”, is located in In Buri District, Sing Buri Province, adjacent to the Chao Phraya River, a very shady temple The past information goes on that There was a pilgrim coming to see this abandoned temple and saw that the surrounding area had dense banyan trees. Therefore telling the villagers to change the name of the temple to Wat Sai. This temple is expected to be built during the Ayutthaya period. The church left only a wall with banyan roots that holds the church wall not to collapse. The roof was shaded by banyan trees because the roof and temple pavilions had deteriorated and were destroyed.
