Designed by Cesar Pelli and built by Dragados,[1] Torre de Cristal (Spanish for Crystal Tower), with a height of 249 meters, is the tallest building in the country.

During the construction of the tower, Repsol decided to change the location of its future headquarters, and the financial institution Caja Madrid (currently Bankia) purchased the building for €815 million in August 2007.

Designed by Henry N. Cobb and built by Obrascón Huarte Lain, the 57-storey Torre Espacio (Spanish for Space Tower) is 224.5 metres (737 feet) tall.

In November 2006, its height surpassed that of the Gran Hotel Bali, thus making it the tallest building in Spain, although it retained that title only for a short time (see above).

The structure was topped out on March 19, 2007 and that evening, Alberto Ruiz Gallardón, mayor of Madrid, attended a firework display to commemorate the event.
