Next to Phra That is the chapel that houses Luang Por Ong Saen, a sacred Buddha statue of the province. It is featured on the reverse of the ten satang coin.
หนองหาร, Nong Han lake
With a depth of three to eight metres, the lake supports agriculture, livestock farming, and a fishery. There are more than 20 islets in the lake such as Ko Don Sawan, the biggest islet where a deserted temple and ancient Buddha images are found.
