Bahla Fort (; transliterated: Qal'at Bahla') is one of four historic fortresses situated at the foot of the Djebel Akhdar highlands in Oman. It was built in the 13th and 14th centuries, when the oasis of Bahla was prosperous under the control of the Banu Nebhan tribe. The fort's ruined adobe walls and towers rise some 165 feet above its sandstone foundations. Nearby to the southwest is the Friday Mosque with a 14th-century sculpted mihrab. The fort was not restored or conserved before 1987, and had fallen into a parlous state, with parts of the walls collapsing each year in the rainy season.
