Atakule is a 125 m (410 feet) high communications and observation tower located in the Çankaya district of central Ankara, Turkey, and is one of the primary landmarks of the city. As the district of Çankaya is itself on a hill, the tower can be spotted from almost anywhere in the city during clear days. The tower's design came from architect Ragıp Buluç and the construction works lasted from 1987 to 1989. The top section of the tower houses an open terrace and a revolving restaurant named Sevilla, which makes a 360-degree  rotation in one hour. On top of Sevilla is another restaurant, Dome, which is non-revolving and located directly under the cupola. Under the terrace is a café, named UFO. The bottom structures house a shopping mall and several indoor and outdoor restaurants. The tower was opened on 13 October 1989 by President Turgut Özal. The tower is now open to visitors after the rebuilding works of the shopping mall were completed. This tower is very similar to Milad Tower in the capital of Iran.

In Turkish, the word ata means "ancestor" (or "father" in Old Turkic), which is often used as a nickname (Ata) for Mustafa Kemal Atatürk, the founder and first President of the Republic of Turkey; while the Turkish word kule means "tower".

The shopping mall adjacent to the tower, Atrium, was also opened on 13 October 1989. It was the first modern mall in Ankara and the second in Turkey after Galleria in Istanbul, which was opened in 1987. The shopping mall was closed due to loss of popularity in the face of competition from an increasing number of more modern shopping malls in the city. It is now demolished and being rebuilt as a contemporary style shopping mall.
