Situated on Rue de France, to the north of Phra Narai Ratchaniwet, this western style viharn was believed to have originally been built by King Narai the Great as a church for Christian envoys. It was subsequently restored by King Narai the Great, who ordered the replacement of Thai windows with Western-style windows with Gothic-designs in the secondary chapel. Later on, the viharn was converted into a Buddhist temple. It contains a large seated Ayutthaya-style Buddha image. In addition, assorted Lop-Buri style Buddha images can be found on the surrounding walls.
