Abu Dhabi is the capital of the United Arab Emirates and of the homonym emirate. The city is located on an island with a triangular shape, 16 km lomng and 10km wide its widest point, very close to the mainland. Abu Dhabi has 921000 inhabitants and is a very modern city, with practically no historic core worth mentioning (the city was a simple fishing village a few decaedes ago). It's essentially a collection of modern buildings and skyscrapers, with wide, multiple lane streets laid out in a grid pattern. It's one of the greener cities in the United Arab Emirates, as it contains many parks and other green areas. Except for the beautiful Sheikh Zayed Grand mosque, Abu Dhabi has no tourist attractions worth mentioning. At the northwestern end there is a nice Corniche road with a pleasant waterfront promenade and beaches. A number of museum are currently being built on Saadiyat island, adjacent to Abu Dhabi. The skyline of Abu Dhabi is still changing, as new skyscrapers are being added on the western end of the Corniche road. Despite its efforts to diversify the economy and boost tourism, Abu Dhabi is a relatively expensive place for tourists with little to offer in terms of attractions and recreation activities.
