Built in the 12th century, about the same time as Banteay Chhmer 6 miles (9 km) to the north, Banteay Tuop, or Army Fortress, is believed to have been a tribute to the army of King Jayavarman VII after it defeated the Cham. Originally adorned with five prasats, the complex now has only four as one collapsed after looting  by petty thieves. The remaining towers, however, are in  good condition, and some of them feature timber from the 12th century.

Transport to Banteay Tuop can be a problem as there are no local buses. Visitors coming from Banteay Chhmer can ask for a moto ride from the market; the round trip takes about two hours; hired taxis are also available for the trip. Banteay Tuop is best visited at dusk; sunsets here are particularly spectacular.
