Wat Ratchaburana is a historically significant Buddhist temple known for its fine main prang. The monastery was founded in 1424 by King Borommarachathirat II on the cremation site of his two elder brothers who died in a royal succession duel. Despite being looted in 1957, the temple still exhibits remains of original stucco work, pictures of mythical creature, Sri Lankan stupas, precious frescoes and Buddha images.

Wat Phra Si Sanphet served as the royal chapel and spiritual centre for the Thais, notable for its role in royal ceremonies, and its three chedis housing the ashes of three Ayutthaya kings. Despite serious damage to its enormous Buddha image during the fall of Ayutthaya (1767), the temple, which has undergone significant restoration efforts, remains a key historical and archaeological site
