Jabreen Castle dates back to 1670. Its design and construction were supervised by the Al Immam BilArab bin Sultan Al Y`aribi (who now rests on the left side of the castle’s main entrance) and was built to resemble the most beautiful palaces of that period. This castle was a beautiful palace for the Immam and his family and a bastion during wartime. It was also a beacon of education and contained many study rooms.
