Torre de Collserola

Torre de Collserola is a member of the World Federation of Great Towers.

The public observation deck, 590 meters above sea level, is reached by an elevator which starts inside the mountain.

The tower is made of: 205 meters of concrete, a tubular steel structure of 38 meters and a steel structure of 45 meters.

The base is 425 meters above sea level. The observation deck is 560 meters above sea level and the total height above sea level is 713 meters.

The elevator speed is 1 m/s and arrives at the observation deck in 2 minutes.

The 13 platforms are between 84m and 152m.

In the top section there are 3 series of 7, 56mm cables running in parralel.

There are 180, 15 mm parralel cables at the first section.

The observation deck is open from 11.00 to 14.30 and 15.30 to 18.00; it is closed on Monday and Thursday. The cost of admission is 4.4 €.

Ordinarily, a conventional reinforced concrete core of 25 meters in diameter would have been required for the 288 meter structure. However a new structural concept was employed: hybrid concrete and steel-braced tubes with a base of 4.5 meters in diameter.

The cables that hold the tower are made of Kevlar, which is transparent to broadcasting signals.

From the observation deck you can see up to 70 kilometres on a clear day.

The weight of the metal structure is 3,000 Tm.

In the basement there is a reception with a bar and photos of other TV towers from around the world.

In order to meet a construction programme of 24 months, the observation deck and other platforms were built on the ground and then jacked inch by inch into position.

The tower was inaugurated on 27 of June 1992.
