Located near San Phra Kan, this historical site features two primary elements: the brick prang and the Great Vihara. The prang showcases Lopburi (Khmer) art, constructed with large bricks, although only the base and partial structure are visible today. In front of the prang stand the walls of a large Vihara built during the reign of King Narai the Great, with relatively well-preserved pillars and wall lines. A key architectural highlight is the pointed-arch windows, a signature style integrating Western artistic influences. Additionally, the base of the site houses sandstone Buddha images and Dvaravati-era historical evidence excavated and displayed around the grounds.
