This old fortress is located at Tambon Talat. Only a few parts of the fortress are still in good condition. It was one of the fortresses of Muang Nakhon Khuaenkhan, serving as a military base at the mouth of the Chao Phraya River. There are many fortresses because King Rama I commanded that the fortresses be built for protecting the kingdom. At present, Muang Phra Pa Daeng Municipality has developed the area of the fortress into a recreational area for the townspeople. The upper part of the fortress displays several old cannons. Trees have been planted all around.
