Ještěd Tower is a 94 meter-tall television transmitter and hotel
integrated into one, built on the top of Ještěd mountain near Liberec in
the Czech Republic. The hyperboloid shape of the structure was chosen
because it naturally extends the silhouette of the hill as well as
resist the extreme climate conditions on the top of the hill. In the
Tower's lowest sections it houses a hotel and a tower restaurant. It was
built in the second half of the 1960s and designed by architect Karel
Hubáček who received the Perret´s Prize of the International Union of
Architects for it.
The tower and the mountain is located
approximately 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 consist of two concentric tubes of varying height in diameters of
5m and 13m, on which individual floors are suspended on a steel
structure, starting with the third story above ground. On the outer
perimeter of the first floor a glazed gallery opens directly tied in to a
spiral access ramp. An internal annulus of the first floor forms the
entrance hall and reception to the hotel, which is dominated by a
suspended staircase leading to an observation restaurant on the second
floor. The next two floors, clad in aluminum, are used for
accommodation. On the third floor are 14 hotel rooms for a total of 56
guests. On the fourth floor are rooms for employees of the transmitter
and the hotel and two three-roomed flats. The area of the fifth to
seventh floors is set aside for the aerials of the transmitting
technology. There is a specially developed laminated cladding, against
extreme weather conditions, in the shape of a revolving hyperboloid. On
the seventh and eighth floors there is a tank for drinking water and
battery-operated back-up power supply. The ninth floor contains the lift
plant room. Above it a special pendulum is installed, whose movement
absorbs the transverse oscillation of the tower.
