Viharn Pra Mongkolborpit is situated on the south of Wat Prasrisanpetch.
The story of pra mongkolborpit is in the era of King Suer, a thunderbolt struck at the tip of the dome which causes damage to the dome. The King ordered to restore the dome and change the roof of the dome to a cathedral and the top of Pra Mongkolborpit was extended during the reign of King Barommakote. During the 2nd fall of Ayuttaya, Viharn Pra Mongkolborpit was ruined by the enemy. After that King Rama 5 ordered to restore this viharn again in the Ayuttaya architectural style. It is a good model of the Buddha image during the end of Ayuttaya reign.
Originally, the east side of the viharn is Sanam Luang, which was used for the cremation ceremony of the Kings and the royalties same as the Sanam Luang in Bangkok.
Viharn Pramongkolborpit is opened on from 8 a.m. to 4.30 p.m. and 8 a.m. to 5 p.m. on weekends and public holidays. The tourists can visit Wat Prasrisanpetch or visit both temples via riding on elephants from Wang Chang Ayuttaya.
