This ancient temple, locally called Wat Na Phra That, is located on the west bank of the Mae Klong River in the town. Its elegant prang or pagoda remains in good condition and was probably copied from Cambodia's Angkor Wat. The prang made of bricks and stones stands on a rectangular base with pathways around the cloisters. The outer stucco designs were made in the reign of King Borommakot of Ayutthaya. Buddha images of Dvaravati, Lop Buri and Ayutthaya periods are placed around the pagoda.

2 kilometres west of Wat Na Phra That on the route to Khao Ngu is Wat Aranyik with a prang identical to that of Wat Na Phra That but smaller in size.
