The Montjuïc Communications Tower ("Torre de Comunicacions de Montjuïc" in Catalan) also known as Calatrava Tower (Torre Calatrava) is a tower located on the Montjuïc Olympic Ring, designed by the prolific and versatile architect and engineer Santiago Calatrava. It was built between 1989 and 1992 for the Olympic Games in Barcelona in 1992 and funded by the Spanish broadband and telecommunications provider Telefónica. The tower was constructed in such a way that its shape resembles an athlete holding the Olympic flame, while the base of the tower is reminiscent of an athlete bending down to pick up a medal. The tower is 136 metres tall and is constructed from steel. Its unique shape and location allow it to function as a giant sundial that casts the time on the Plaza Europa which is located just below. Its base is covered with trencadís, Gaudí's mosaic technique created from broken tile shards.
