Collserola Tower, located in the Spanish Barcelona certainly stands out from other such structures. The first project to build a grand transmission tower in the heart of Catalonia was created in 1987. In five years, the Olympic Games were to take place in the city. Barcelona did not yet have a broadcast mast that could overcome the communication chaos of the Olympic city. In addition, the tower was to become a symbol of the city apart from the stadium.
The project was entrusted to the genius British architect Sir Norman Foster. He and his associates as usual stood up to the task. A tower project has been created which the world has not yet seen.
As the construction site, the Turo de la Vilana was chosen as 445 m above sea level. Thanks to this, the top of the structure is located at an altitude of 733 m. In addition, the mountain is built of very strong rock, occurring at the minimum depth.
Construction began in March 1990. At the beginning, as always, foundations for the tower and its lashings were created. Then the core of the building was built, the deck was decked and the transmitting equipment was installed. The opening took place on June 27, 1992. Soon after the Olympic Games were played.
The main element of the structure is a reinforced concrete core with a diameter of 450 cm. It is 205 m high and its foundations reach a depth of 5 m. A steel structure with a height of 83 m is placed at the top of the core. It has a conical shape and is held vertically by ropes attached to the deck. Transmitting antennas are mounted to it.
A twelve-story deck with a height of 83 meters has been attached to the core. Its lowest part is located 60 meters above the ground, it was made entirely of steel and weighs nearly 3,000 tons.
The entire structure holds eight steel wire ropes vertically. Each of them has a diameter of 56 mm (1.96 inches).
An observation platform has been located at an altitude of 135 meters. In good weather there is a beautiful view within a radius of 70 km.
The deck can be reached by a lift located in the core of the structure. It has a speed of 36 km / h, and can carry 250 people per hour.
