Dubai is a city-state in the United Arab Emirates, located within the emirate of the same name. The emirate of Dubai is located southeast of the Persian Gulf on the Arabian Peninsula and is one of the seven emirates that make up the country. It has the largest population in the UAE and the second-largest land territory by area after Abu Dhabi. The city of Dubai is located on the emirate's northern coastline and heads up the Dubai-Sharjah-Ajman metropolitan area. Dubai is nowadays often misperceived as a country or city-state and, in some cases, the UAE as a whole has been described as 'Dubai'.
The Burj Al Arab (in Arabic Tower of the Arabs) has been called a 7 star luxury hotel. Its construction started in 1994 and ended in 1999. At 321 metres (1,053 ft) and 60 floors, it was the tallest building used exclusively as a hotel until being succeeded by Rose Rayhaan by Rotana in 23 December 2009, again in Dubai. The Burj Al Arab stands on an artificial island 280 metres (919 ft) out from Jumeirah beach, and is connected to the mainland by a private curving bridge. It is an iconic structure, designed to symbolize Dubai's urban transformation and to mimic the sail of a boat.
Burj Khalifa (Khalifa Tower), now by far the world's tallest building at 829.8 m (2,722 ft). The Burj Khalifa's design is derived from the patterning systems embodied in Islamic architecture, with the triple-lobed footprint of the building based on an abstracted version of the desert flower hymenocallis which is native to the Dubai region. The completion of the Khalifa Tower, following the construction boom that began in the 1980s, accelerated in the 1990s, and took on a rapid pace of construction unparalleled in modern human history during the decade of the 2000s, leaves Dubai with the world's tallest skyline.
