The fort, also known as Husn Al Heem, was named after the state of Nakhal that exists above the old village of Nakhl.

Initially built as a protective measure for an area oasis and nearby trade routes, it passes through the regional capital of Nizwa.

[2][3] 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.

[4] It is situated on a rocky prominence at the foot of Jebel Nakhal, a spur of the main Western Hajar range.
