The northern area is bounded north by the Ayutthaya city district boundary (an imaginary line from the Thung Makham Yong intersection to, but not including, Wat Phai Somnarin) to the east by the Lopburi River, to the south by Khlong Mueang and the west by the Chao Phraya River.

Several fields characterise the area, being Thung Makham Yong, Thung Phukhao Thong, Thung Lum Phli, Thung Khwan, Thung Kaeo, Thung Pho Sam Ton and the Phaniat area. The zone contains a total of (later) temple sites.
