In the background Montjuic Telecommunications Tower could be seen. It was built for Telefónica in the heart of the 1992 Olympic site, to carry coverage of the Games. The building is 136m tall and the overall form of the tower is based on a Santiago Calatravas (architect of the tower) sketch of a kneeling figure making an offering. The base on which the figure 'kneels' is covered in broken glazed tiles in recognition of Gaudi. The orientation of the tower means that the shadow of the central needle on the circular platform acts as a (rather impractical) sundial.
