Abu Dhabi

Abu Dhabi is the capital of the United Arab Emirates. The city is on an island by the sea.

Abu Dhabi is the capital of the United Arab Emirates. It began in the 1700s as a small settlement around fresh water on an island, guarded by a coral-stone watchtower. Before oil, it relied on fishing and pearl diving; since the 1960s, money from oil has turned it into a city of towers. An official estimate gave the city about 1.75 million people in 2023.

Abu Dhabi grew from a settlement founded after water was found on the island around 1761. Its ruler moved his seat of power to the island in 1795, with the fort of Qasr Al Hosn as his seat of government, and the city became the federal capital of the United Arab Emirates, formed in 1971. An official estimate gave the city about 1,750,000 people in mid-2023, and the Statistics Centre Abu Dhabi estimated 2,823,340 people in the wider Abu Dhabi region in 2024.

Discover Abu Dhabi

Abu Dhabi is the capital city of the United Arab Emirates. The city sits on an island in the sea.

It has many tall towers that shine at night.

Abu Dhabi is the capital of the United Arab Emirates, a country of seven emirates on the Arabian Peninsula. The city has the same name as the largest emirate, Abu Dhabi, and it stands on an island off the coast.

The Statistics Centre Abu Dhabi estimated 2,823,340 people in the Abu Dhabi region, one of the emirate's three regions, in 2024. For the city itself, an official estimate gave about 1.75 million people in 2023.

City Population's tables from the Statistics Centre Abu Dhabi give the Abu Dhabi region 1,310,485 people in 2011 (an estimate), 2,595,390 in the census of 20 September 2023 and 2,823,340 in the estimate for 20 September 2024. The whole emirate counted 3,847,585 in the revised 2023 census.

For the city alone, the cities table lists 243,257 people in the 1980 census, 398,695 in 1995 and an official estimate of about 1,750,000 for mid-2023.

A coral fort and shining towers

Abu Dhabi has an old fort. It is made of coral and stone from the sea.

The city also has tall towers and a hotel with domes.

Qasr Al Hosn began as a watchtower built of coral and sea stone, which guarded the way onto the island and the small community growing around it. More towers were added later and joined into a fort, which became the ruler's home and seat of government.

The modern city has many tall towers. In the photo, the Emirates Palace, a hotel with many domes that opened in 2005, glows gold in front of the Etihad Towers, a group of five towers whose tallest is 305 meters high.

Qasr Al Hosn's own history says a sheikh of the Bani Yas tribe from the Liwa Oasis ordered the first watchtower, of coral and sea stone, to watch over coastal access to the island. Between 1793 and 1816 more towers were built and linked into a defensive enclosure, the seat of government and the ruler's family home. After the first oil concessions in 1939, a palace was built around the old fort walls, tripling the site. A later conservation project dealt with a white render that had trapped moisture on the original coral stone bricks, revealing the original foundation again.

Wikidata dates the Emirates Palace hotel's opening to February 2005, lists 305 m for the tallest of the five Etihad Towers (inception 2011), and 342 m for the ADNOC Headquarters tower (inception 2015), seen still under construction at the left of the photo.

Water, pearls and oil

Long ago, people found fresh water on the island and built a little town there.

People dived into the sea for pearls. Later, oil was found, and the town grew into a big city.

People of the Bani Yas tribe found fresh water on the island around 1761, and a small settlement grew there. In 1795 their ruler moved his seat of power to the island from the Liwa Oasis inland. By the late 1800s Abu Dhabi had more than 400 pearling boats. Before oil, people dived for pearls in summer and herded animals or farmed at oases the rest of the year.

Money from oil exports began to transform Abu Dhabi in the 1960s. In 1971 the emirates joined to form the United Arab Emirates. Abu Dhabi is its federal capital.

The Encyclopedia of the Modern Middle East and North Africa (Malcolm C. Peck, updated by Anthony B. Toth) says a settlement named Abu Dhabi, 'Land of the Gazelle', was founded after water was discovered around 1761, and a small fort was built over its well. Qasr Al Hosn's history adds that the water lay not in one well but in shallow pools called 'scrapes', and that the seat of power moved from Liwa to the island in 1795.

In the 19th century the rulers signed treaties placing them under British protection, and nearby oyster banks drew many pearling ships to the town. Oil revenues brought rapid change from the 1960s; after Britain announced in 1968 that its protection would end, the emirates formed the UAE, and Qasr Al Hosn's history notes that meetings to negotiate the union were held in its National Consultative Chamber in 1971.

Through the years

A city on an island

Abu Dhabi is on an island, so there is water all around it.

Long ago, a watchtower kept watch over the way onto the island. Now Abu Dhabi also has an airport with planes to other countries.

The coast of the emirate of Abu Dhabi has many islands, and the capital city stands on one of them. The first watchtower was placed so that it overlooked the way onto the island from the coast.

The emirate's oil wealth has paid for modern airports, transportation and communications, and Oxford's World Encyclopedia notes that Abu Dhabi has an international airport and a container port for cargo ships.

The Encyclopedia of the Modern Middle East describes the emirate's land as mostly flat and rocky, with dunes inland and salt flats and many islands along the coast; Abu Dhabi City occupies one of these islands. Qasr Al Hosn's first watchtower 'overlooked and controlled coastal access to the island'.

The same encyclopedia says oil and gas revenues funded modern international airports and a modern communications and transportation network, and Oxford's World Encyclopedia notes Abu Dhabi's international airport and modern container port.

Hot summers, mild winters

Summers in Abu Dhabi are very hot. Winters are mild.

It hardly ever rains, and almost never in summer.

The averages the World Meteorological Organization lists for Abu Dhabi (1982–1991) show daytime highs of about 42 °C in July, the hottest month, and about 24 °C in January, the coolest. January nights average about 12 °C.

Very little rain falls: about 89 millimeters in an average year, most of it from December to March. February is the wettest month, with about 42 millimeters, and from May to October almost no rain falls at all.

The WMO table, supplied by the UAE's National Center of Meteorology for 1982–1991, gives average highs of 42.0 °C in July and 41.5 °C in August, and 23.8 °C in January; average lows run from 11.8 °C in January to 28.7 °C in August.

The monthly rainfall averages add up to about 88.9 mm a year, on about 12 rain days (0.2 mm or more). February brings the most (42.0 mm), and the six months from May to October together average only 0.1 mm.

From pearls to oil and museums

Long ago, people in Abu Dhabi dived for pearls and fished.

Then oil was found. Now the city has tall buildings, universities, hospitals and museums.

Abu Dhabi began as a settlement that relied on fishing and pearling. The first oil concessions, agreements letting companies look for oil, were negotiated in 1939, and from the 1960s oil exports transformed the emirate. The Encyclopedia of the Modern Middle East credited the emirate with about 90 percent of the UAE's oil reserves.

Oil money paid for universities, hospitals, museums, hotels and office towers. The Louvre Abu Dhabi, an art museum, opened in November 2017.

The Encyclopedia of the Modern Middle East credited the emirate with 90 percent of the UAE's roughly 100 billion barrels of oil reserves and 60 percent of its gas reserves, and said these revenues funded international airports, universities, hospitals, museums, towering hotels and office buildings 'where only fifty years earlier there were simple palm-frond huts and dusty paths'.

Qasr Al Hosn's history places the first oil concessions in 1939, negotiated with Great Britain. Wikidata dates the opening of the Louvre Abu Dhabi to 8 November 2017.
