During the Ayutthaya period, kilns were located along the banks of Khlong Sra Bua and across the area, along what is now Khlong Hua Ro, a section of the old Lopburi River. The Description of Ayutthaya mentions that above Ayutthaya's city island, there were five villages, two of which produced pottery and various kinds of tiles. This area was called Thung Khwan, with the opposite area being Thung Kaeo. Thung Khwan is west of Khlong Sra Bua, and Thung Kaeo is east of Khlong Sra Bua, mainly in the present-day Khlong Sra Bua Sub-district.
