Arad Fort!

Was close to the airport and happened to pass by the Arad Fort. Quite a spectacular looking structure especially at night. Will have to go back:-)

From Wikipedia:

Arad Fort is one of Bahrain's most important fortified castles. The Fort was built in the style of Islamic forts at the end of the 15th and early 16th centuries. Due to its strategic location overlooking various sea passages of Muharraq Island, Arad Fort was used as a defensive fortress throughout history, from the time Bahrain was occupied by the Portuguese in the 16th century to the reign of Shaikh Salman Bin Ahmed Al-Khalifa in the 19th century. Arad Fort was most recently restored in the 1980s, a process which took three years. In order to maintain the historical authenticity and value of Arad Fort, exclusively traditional materials were used, such as coral stone, lime and tree trunks.[2]

It is believed that the fort was used by the Omanis during their brief occupation of Bahrain in 1800, and it is located adjacent to the strategic waterways between Bahrain Island and Muharraq Island.

Little is known of the fort's history, and there is no firm evidence of the precise date of construction, but comprehensive excavations have been undertaken in order to discover its past.

The fort is open for a fee.
