Wat Sothon Wararam was built in the late Ayutthaya Period during the reign of King Narai the Great, with its original name being Wat Hong. The temple houses Phra Phutthasothon, a much-revered Buddha image of Chachoengsao created by a craftsman from Lanchang. The image sits in the meditation position and is 1.65 meters in width and 1.48 meters in height.
