Mouth of the old Bang Kaeo River

The Bang Kaeo River is a defunct river which river bed at present still can be traced back along the different irrigation canals east of the Chao Phraya River. In the Ayutthayan era the river had its source at the split of the Chao Phraya River near Bang Kaeo in the same way the Lopburi River had its origin at Bang Phutsa. The river ran in the present Bang Kaeo Canal for 13.5 kilometers and turned southwest at Wat Han Sang. After 500 meter it ran into the present irrigation canal running through Hua Phai of Maha Rat district, Han Sang, Ta Nim, Bang Nang Ra, Khwan Mueang and Phut Lao of Bang Pahan district. From Ban Nonsi in Phut Lao sub-district, the river turned southwest towards Ban Mai and then turned southeast towards Ayutthaya. The Bang Kaeo River joined the old Lopburi River at Hua Laem at the northwestern point of the city in front of Sat Kop Fortress.
