Prasat Hin Phanom Wan was built during the 10th and 11th centuries, and like most other Khmer temples, its main entrance faces east; In the past it was dedicated to Lord Shiva, so later many Buddha images were placed inside it, and today there is a large Buddha image in the main tower. It's nice to walk around the temple complex, and it's worth noting that it's not as impressive as the other large temples, but it's definitely worth a short visit.
