The structure of the fort in itself is worth visiting and inside, there is a little history of the fort and the origins of the ruling family. The best part in the displays and presentations is the story about Mubarak bin London (Wilfred Thesiger).
It was built in 1891 to defend the city's people and palm groves, it was the former headquarters of the Oman Trucial Scouts, the force that protected the surrounding mountain passes. It also served as a residence for the local governor.
