The Thung Setthi Fort is located on Phahonyothin Road alongside Highway No. 101, just before reaching the city of Kamphaeng Phet, slightly outside of Nakhon Chum to the south. This large ancient site features a laterite wall forming its structure, with remnants of a stele still visible. The fort, constructed from laterite, measures 83.5 meters wide and has a square shape, standing approximately 6 meters tall. Each of its four sides has a central entrance and exit, and there is enough space in the inner rampart for people to walk past each other. Below the rampart, at the base of the fort, there are connected chambers with openings near the ground, also built from laterite. The outer wall is tall, and at the very top, it is adorned with stele-like structures. Beneath each of these stele are openings that likely served as gunports, while the four corners of the wall extend outward to form square bastions. The lower part of the wall has small, rounded openings. The construction of Thung Setthi Fort demonstrates remarkable strength, though the northern side has been partially dismantled, leaving only three walls. In this area, there are several ancient temples, such as Wat Nong Pikul, Wat Soong Ko, and Wat Nong Langa. Of particular significance to those who collect amulets is that this region is known for finding famous Buddhist amulets from Kamphaeng Phet.
