Located in the area of the Tak Khwai Channel, Ban Thai Niyom Phattana, in the Bum Dai Subdistrict, this single-shrine sanctuary sits atop a ridge about 10 meters away from the high cliffs of the Phnom Doulak mountain range. Known as the Tak Khwai Temple, it faces east and is designed in a cruciform plan with a low base. The lower part is constructed of laterite stone, while the upper portion is made entirely of sandstone. The roof of the main sanctum is shaped like a series of lotus petals, tiered in five levels, with the gables forming a steep pitch that meets the facade on all four sides. Inside, a single sculpture resembling a Swayambu-linga can be found. The Tak Khwai Temple is a solitary shrine with no accompanying structures or buildings, leading to the belief that it was never completed. Based on its architectural style, it is estimated to have been constructed during the late Angkor Wat period, transitioning into the early Bayon period, between the reign of King Suriyavarman II and King Jayavarman VII. Visitors to this site will need to be prepared for a hike, as access by car is not possible. The journey to the temple requires a 3 to 4-kilometer walk on foot.
