The tower is 371.5 m (1073 ft) tall; its 114 m metal aerial reaches 1000 meters above sea level. It has two observation decks at the height of 146 m and 252 m, which are accessible by two high-speed elevators. It is however not open to the public. The tower was built by the architects Terziev, Savchenko, Akimov and Ostroumov. Since Almaty is particularly vulnerable to earthquakes, the TV tower was designed to withstand earthquakes up to a strength of 10 on the Richter scale.
