The Barcelona Tower or "Torre de Collserola" is a uniquely designed tower located on the Tibidabo hill in the Serra de Collserola, in Barcelona, Catalonia, Spain. It was designed by the architect Sir Norman Foster and by the Spanish civil engineers Julio Martínez Calzón and Manuel Julià Vilardell. This emblematic tower was built in 1991 for the 1992 Summer Olympics. It features a pod for floor space like many towers but uses guy wires for lateral support like a mast. Mainly used as a TV/Radio broadcast and telecomunications relay, this futuristic design provides the highest viewpoint over the city. The top antenna reaches 288.4 m (946 ft) and the top of the pod, which has thirteen floors, reaches 152 m (499 ft). The highest point of this tower is the highest place one could find in the city of Barcelona. The tenth floor of the pod is usually open to the public (not now due to the pandemic restrictions).
