Fort Jesus was captured and recaptured at least nine times between 1631, when the Portuguese lost it to the Sultan Yusuf ibn al-Hasan of Mombasa, and 1895 when it fell under British rule and was converted into a prison.
After the Portuguese recaptured it from the Sultan in 1632, they refurbished it and built more fortifications, subsequently making it harder for the fort to fall.
The fort was subject to an epic two-year siege from 1696-98 by the Omani Arabs, led by Saif bin Sultan.
Some of the historical structures still standing in the fort include Oman House, which was the house for Sultan who governed the East African coast.
