The Tha Phra Temple Water Market is located in front of Wat Thammamun Worawihan in Thammamun Sub-district, Chai Nat City. A bridge spans the Chao Phraya River, connecting two districts: Chai Nat and Wat Sing. This bridge has provided local residents with a valuable space beneath it, serving as a shaded area to escape the sun and rain. Here, community members engage in commerce, selling both food and agricultural products. Over time, the trading area has expanded, becoming an important marketplace for the community.
