The Zizkov Television Tower is a uniquely-designed tower built in Prague between 1985 and 1992. It stands high above the city's traditional skyline from its position on top of a hill in the district of Zizkov, from which it takes its name.The structure of the tower is unconventional; it consists of three concrete pillars that carry cabinets for the transmitters, a restaurant and cafe, and three observation rooms. From afar, the tower resembles a rocket launchpad. The tower is 216 metres (709 feet) high, with the observation decks at 100 metres (328 feet) and the tower restaurant and cafe situated at 63 metres (207 feet) in the lower 'pods'. Elevators, equipped with speedometers, transport passengers to the different levels at a rate of 4m/s. The tower weighs 11800 tons and is also used as meteorological observatory. It is a member of the World Federation of Great Towers.
