List of tallest buildings and structures
The tallest artificial structure is Burj Khalifa, a skyscraper in Dubai that reached in height on January 17, 2009. By April 7, 2008 it had been built higher than the KVLY-TV mast in North Dakota, USA. That September it officially surpassed Poland's Warsaw radio mast, which stood from 1974 to 1991, to become the tallest structure ever built. Guyed lattice towers such as these masts had held the world height record since 1954.
History of the world's tallest buildings
Skyscrapers used primarily or exclusively as hotels or residential space are generally shorter than office and mixed-use buildings, with only a few supertall buildings of the residential or hotel types among the 100 tallest skyscrapers. The tallest completed residential building (minimum 85% residential) is 432 Park Avenue in New York City, followed by the Princess Tower and 23 Marina, both in Dubai. The tallest completed hotels (primarily hotel space) are the Gevora Hotel, the JW Marriott Marquis Dubai twin towers, the Rose Tower, and the Burj Al Arab, all located in Dubai.
