Khasab Castle lies in the quiet fishing town of the same name, in the Musandam Governorate in Oman. Khasab Castle was built by the Portuguese in the beginning of the 17th century. There is evidence to suggest that it was built on the ruins of an earlier indigenous fort. Some 25 years after its construction the Portuguese were expelled from Oman and the castle was taken over by Omani rulers who modified it to their own military needs. When it was built the castle was situated next to the beach. At present the sea has receded and new land has been made and developed in front of it. The castle has a square ground plan with 1 round corner tower and 3 rectangular ones. It has a central, round tower in its center. In 1990 Khasab Castle was restored. It now houses a museum. The above information was all the historical information I was able to find about the castle. If you know more; please mail me. At present Khasab Castle can be visited for a small fee. This is a very nice castle. And if you are there, don't forget to visit nearby Al Kamazra Castle. There is a walking path starting at Khasab Castle, supposedly leading to Kamazra but when I followed it, I got lost, so it's better to take the car. Bani Sanad Fort is also nearby.
