Wat Maha That is an important temple of the province in the town. The building of importance here is Phra That Yasothon or Phra That Anon, an ancient square pagoda with the top similar to that of Phra That Phanom. The architecture is in the Laotian style which was popular in the late Ayutthaya to early Rattanakosin periods. The pagoda houses the relics of Phra Anon. A state minister from Si Sattana Khanahut (Vientiane) who took migrants to settle here about 200 years ago constructed it around 1778.
Another historical site within the compound is the scripture hall that is in the Isan art style. The doorway and the door are beautiful carved woods with exquisite lacquer designs. The designs on the walls show a mixture of art from the Central Region. Built during the reigns of Rama IV and Rama V of the Rattanakosin period, the hall stores scriptures on dried palm leaves and art objects from Vientiane.
