Arad Fort was built in the typical style of Islamic forts during the 15th century before the Portuguese invasion of Bahrain in AD 1622. This fort is one of the compact defensive forts in Bahrain. In its present location, it overlooks various sea passages of Muharraq shallow seashores. In the past, there was an inaccessible marine channel which was controlled by the local people to prevent ships from breaking through to the island where the fort is located. The Fort is close to the Bahrain International Airport, the fort has been extensively renovated and presents a magnificent sight when it is illuminated at night.
