Bahla Fort

Bahla Fort 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.

The fort became a UNESCO World Heritage Site in 1987. It was included in the List of World Heritage Sites in danger from 1988. Restoration works began in the 1990s, and more than £6m were spent by the Omani government from 1993 to 1999. It remained covered with scaffolding and closed to tourists for many years. It was removed from the list of endangered sites in 2004
