Nakhal Fort (Arabic: قلعة نخل Qalʿa Nakhal) is a large fortification in the Al Batinah Region of Oman. It is named after the Wilayah of Nakhal. The fort houses a museum, operated by the Ministry of Tourism, which has exhibits of historic guns, and the fort also hosts a weekly goat market.
The fort is approximately 120 kilometres (75 mi) to the west of Muscat, the capital of Oman, at the entrance of Wilayt Nakhal in Wadi Ar Raqeem. It is situated on a rocky prominence at the foot of the Mount Nakhal, a spur of the main Western Hajar range. It is to the northeast of Al Jabal Al Akhdar. Nakhal Fort is surrounded by orchards of palm trees. Its battlements provide a view of the Al-Batinah Region. The ancient Nakhal village is below the fort and close by is A'Thorwarah, the warm springs of Nakhal, a part of the oasis. Nakhal Fort is one of several fortifications in the Al Batinah Region, the others being Al Hazim, Al-Sifalah, Rustaq, and Shinas forts.
Built in the architectural style of the Sultanate of Oman, it does not follow a particular pattern, as it was designed around an irregularly-shaped rock and subsumes some rock exposures into its structural layout in the interiors. The fort is simple in form and the main entrance gate has been designed with defense considerations. The entry gate, approached through a flight of steps, features a spiked, wooden, double door. Ogival arches are seen past the entrance gate, leading to the main residential buildings. The fort's exterior walls have niches with pointed arches in equilateral geometric design and have small rectangular and circular openings to permit sun light exposure. The mosque inside the fort is of simple design.
