The prang at Wat Phutthai Sawan is located in the middle of the compound. It is surrounded by a cloister, that houses rows of Buddha images. The prang is built on an indented pedestral with 2 staircases in the east and the west. There are two mandapas to the north and the south of the prang. The prang itself houses the main Buddha image.
Wat Phuttha Sawan was constructed by King U-Thong just south of the Chao Phraya River. Since built be the first King of Ayutthaya, it is an important temple, and has frequently been restored. Originally smaller prangs would have flanked the present main prang.
