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, also known as Husn Al Heem, was named after the state of Nakhal where it exists above the old village of Nakhl. It has a history which dates back to the pre-Islamic period. Over the centuries, it underwent many renovations and improvements. It was re-built by Omani architects in the 17th century. Built as a protective measure for an area oasis and nearby trade routes, it passes through the regional capital of Nizwa. The gateway and towers seen now were extensions built in 1834 attributed to imam Said bin Sultan. In 1990, it was fully renovated. Imams of Wadi Bani Kharous and the Ya'arubah dynasty resided here in the past.
he 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 Jebel Nakhal, a spur of the main Western Hajar range. It is to the northeast of Jabal Akhdar also called green mountain. 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 the warm springs of Ain A'Thawwarah. Nakhal Fort is one of several fortifications in the Al Batinah Region, the others being Al Hazim, Al-Sifalah, Rustaq, and Shinas forts.

During recent renovations the fort has been fitted with traditional furniture, handicrafts and historic artifacts.
