Wat Phra Si Sanphet is one of the most important and grandest temples in the Ayutthaya Historical Park.
Built in the 15th century during the reign of King Ramathibodi II, it served as the royal temple within the grounds of the old Royal Palace — much like Wat Phra Kaew in Bangkok today.

The temple was used exclusively for royal ceremonies and did not house any monks.
Its most distinctive features are the three large bell-shaped chedis, which enshrine the ashes of three Ayutthaya kings. These elegant structures have become a symbol of Ayutthaya’s ancient glory and architectural excellence.
