This Muang Singh must have been an important outpost of Angkor as it was mentioned in the Prasat Phra Khan inscription made during the reign of King Jayavarman VII. At present, Muang Singh on the bank of Khwae Noi river is included in Muang Singh sub-district, Sai Yok district, Kanchanaburi Province. The vestiges of the ancient city comprise several layers of rectangular walls and moats, having Prasat Muang Singh in the middle. Other three lesser monuments in ruins are also found in the area. From the main monument has been discovered a number of Mahayana Buddhist images.
