On Highway No.3 (Sukhumvit) just opposite the Trat Hospital is a turn into Plai Khlong Road which leads to Wat Bupharam , a distance of two kilometres. Built in circa 1648 during the Ayutthaya era, it features the oldest wooden Viharn in the country.
The architectural style and the remaining wall murals are of early Rattanakosin influence with a mix of Chinese touch. The temple's museum houses scores of valuable ancient relics, particularly the Holy Relic, Buddha statues in different postures and Chinese and European porcelain items. All these point to commercial and cultural exchanges carried out between the different parts of the world in the past.
