The Burj al-Arab is a luxury hotel in Dubai, United Arab Emirates. At 321 metres (1,053 feet), it is the tallest building used exclusively as a hotel. It stands in the sea on an artificial island 280 metres (919 feet) away from the beach in the Persian Gulf, connected to the mainland only by a private curving bridge.
The Burj al-Arab does not have ordinary rooms; rather it is divided into 202 duplex suites. The smallest suite occupies an area of 169 square metres (1,819 square feet), and the largest one covers 780 square metres (8,396 square feet). It is one of the most expensive hotels in the world to stay in. The prices for the least expensive suites are in the range of $1,000 to over $6,000 a night. The most expensive suites can cost over $15,000 a night.
It was built to resemble the sail of a dhow, a type of Arabian vessel. Two "wings" spread in a V to form a vast "mast", while the space between them is enclosed in a massive atrium. The hotel rests on an artificial island constructed 280 m (920 ft) offshore. To secure a foundation, the builders drove 230 forty-metre (130 ft) long concrete piles into the sand.
