The old town of Suphan Buri was located at Tambon Rua Yai on the western bank of the Tha Chin River. Until today, an earth wall and moat remain between Wat Pa Lelai and the City Pillar Shrine. On the western side, double walls were strongly built with a moat outside, then a mound and the wall. The inner wall is 3,500 metres long on the north-south direction, and its width stretches for a kilometre to the river. The wall on the eastern side has all disappeared as it was dismantled during the reign of King Maha Chakkraphat. The Fine Arts Department rebuilt the town gate, on Malai Maen Road, on the location believed to have been the site of an old gate.
