Žižkov Television Tower
The Žižkov Television Tower ((チェコ語:Žižkovský vysílač)) is a unique transmitter tower built in Prague between 1985 and 1992. Designed by the architect Václav Aulický and the structural engineer Jiří Kozák,〔(【引用サイトリンク】title=Žižkovská televizní věž )〕 it stands high above the city's traditional skyline from its position on top of a hill in the district of Žižkov, from which it takes its name. The tower is an example of high-tech architecture.
==Characteristics==
The structure of the tower is unconventional, based on a triangle whose corners are growing up in steel columns, consisting of three tubes with a double steel wall, filled with concrete. They support nine 'pods' and three decks for transmitting equipment. One of the three pillars extends considerably higher than the others, and this provides both the necessary height for some antennas, along with the structure's rocket and gantry appearance. In its time it was a unique technology, which authors have patented. In total, the tower stands 216 metres (709 feet) high.
Three of the pods, positioned directly beneath the decks at the top of the tower, are used for equipment related to the tower's primary function and are inaccessible to the public. The remaining six pods are open to visitors, the highest of which are observation rooms at 100 metres (328 feet), providing a panoramic view of Prague and the surrounding area. The lower three, approximately half-way up the length of the pillars at 63 metres (207 feet), house a recently refurbished restaurant and café bar. Elevators, equipped with speedometers, transport passengers to the different levels at a rate of 4 m/s. The tower weighs 11,800 tons and is also used as a meteorological observatory. It is a member of the (World Federation of Great Towers ).
