Wat Pho Chai (วัดโพธิ์ชัย) Luangpho Phra Sai, a sacred Buddha image of the town which is respected by the people of Nong Khai, is housed here. Every year on the full moon day in the seventh lunar month, the people of Nong Khai always hold a rocket merit-making fair or Bun Bang Fai to worship Phra Sai at Wat Pho Chai.
