Strategically located as a sea passage, Arad fort is a typical example of Omani military architecture at the end of the 15th and early 16th centuries. This fort was once the site of fierce battles and underwent different construction phases. All though it is not clear when it was constructed it has played a major role in the defense of Bahrain against marauders through the centuries. It was restored in the 1980s using only authentic material.  It is nicely illuminated at night and hosts seasonal festivals throughout the year.
