Torre de Collserola

Torre de Collserola (or Torre Foster) is a uniquely designed tower located on the Tibidabo hill in the Serra de Collserola, near Barcelona, Catalonia, Spain. It was designed by architect Lord Norman Foster, and built in 1992 for the 1992 Summer Olympics. It features a pod for floor space like many towers but uses guide lines for lateral support like a mast. Mainly used as a TV and radio transmitter, this futuristic design provides the highest viewpoint over the city. The top antenna reaches 288.4m (946 ft) and the top of the pod, which has thirteen floors, reaches 152m (499 ft).

The tenth floor of the pod is open to the public.
