All that remains visible of Ku Bueng Jiew (กู่บึงจิว) is a single carved sandstone pedestal with two holes in it. Locals believe this stone now covers a naga hole. The large Buddha that's inside the sala in front of the naga hole was built over all the laterite blocks that remained from the Khmer temple. Its age is unknown. Locals call the site Prang Ku.
