Banan Hill, or Phnom Banan, is a small hill about 400 meters high around 21 kilometers south of Battambang. Atop the hill is the province's best preserved Angkor era temple, Prasat Banan. A grand stone staircase leads up the side of the hill to the temple. There are 358 steps, so be prepared to sweat.
The temple complex consists of five towers arranged in a cruciform pattern. It was started in the mid-eleventh century but left unfinished until around the turn of the thirteenth century. There are some fine reliefs that can still be seen on the sides of the towers.
