Qasr Al Hosn Fortress (White Fort) – the oldest stone building in Abu Dhabi and the symbolic birthplace of the emirate, located in the city center at the intersection of 2nd and Hamdan streets. Built in 1761 as a watchtower to protect a freshwater source, it became the residence of the ruling Al Nahyan family and the center of government of the emirate until 1966. Today it is a cultural complex with a museum, library and research center, where tourists and residents come to touch the history of the United Arab Emirates and see the place from which modern Abu Dhabi began.
History of Construction
Construction of the fort began in 1761 by order of Sheikh Diyab bin Isa of the Bani Yas tribe, when gazelle hunters discovered a freshwater spring on the island. Originally it was a round watchtower made of coral stone and shell rock, which reflected sunlight due to crushed sea shells added to the mortar – hence the name "White Fort". In 1793, Sheikh Shakhbut bin Diyab turned the tower into a full-fledged fortress, which served as the residence of the rulers and the center of power for more than 170 years. In 1939-1945, the Outer Palace was built with revenues from the first oil concession, turning the complex into a royal residence with two entrances – northern for men and southern for women. In 1968, Sheikh Zayed bin Sultan Al Nahyan turned the fort into a research and documentation center. In 2018, after an 11-year restoration, Qasr Al Hosn opened as a museum.
