The Ještěd Tower is a television signal transmitter and hotel (website) integrated in a single structure of 94 meters high, built on the top of the Ještěd mountain near Liberec in the Czech Republic. The hyperboloid shape of the structure has been chosen because it extends naturally to the silhouette of the hill, as well as for its resistance to the extreme climatic conditions at the top of the hill. In the lower sections of the tower there is a hotel and a restaurant. It was built in the second half of the 1960s and designed by the architect Karel Hubáček who received the Perret Prize from the International Union of Architects for it.
The tower and the mountain is located about 6 kms from the center of Liberec and serves as a dominant attraction in the city. The monument is accessible by road and also by cable car from the foot of the mountain.
The tower consists of two concentric tubes of different height in diameters of 5m and 13m, in which individual plants are suspended in a steel structure, starting with the third floor above the ground. On the outer perimeter of the first floor an open glazed gallery directly linked to a spiral access ramp. An inner ring on the first floor forms the entrance hall and reception of the hotel, which is dominated by a suspended staircase that leads to an observation restaurant on the second floor. The next two floors, clad in aluminum, are used for housing. On the third floor there are 14 rooms for a total of 56 guests. On the fourth floor there are rooms for the employees of the station and the hotel and two floors of three rooms. The area from the fifth to the seventh floor is reserved for antennas for transmission technology. There is a specially developed laminated covering, against extreme weather conditions, in the form of a rotating hyperboloid. On the seventh and eighth floors there is a drinking water tank and a reserve battery power supply. The ninth floor contains the engine room of the elevator. Above it a special pendulum is installed, whose movement absorbs the transverse oscillation of the tower.
