Khasab Fort stands at the edge of the town centre, a solid square structure with round corner towers whose walls have been repeatedly repaired over four centuries of use. The interior courtyard is shaded and quiet, a relief from the sun outside. The museum inside covers local life before oil — fishing, pearl diving, and the ancient frankincense trade routes that passed through the Strait of Hormuz.
The fort is open Saturday to Thursday; check current hours locally as they vary by season. Entry is free or a nominal fee. The rooftop offers good views across the harbour and down the coast toward the khors.
