Cuatro Torres Business Area (CTBA) (Spanish for Four Towers Business Area) is a business district located in the Paseo de la Castellana in Madrid, on the former Ciudad Deportiva of Real Madrid. The area contains the tallest skyscrapers in Madrid and Spain. The construction of the buildings finished in 2008. The complex was formerly known as Madrid Arena. Designed by Henry N. Cobb and built by Obrascón Huarte Lain, the 57-storey Torre Espacio (Spanish for Space Tower) is 224.5 metres (736 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. 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.
Designed by Lord Foster, and built by a joint venture of Dragados and Fomento de Construcciones y Contratas, the 45-storey Torre Caja Madrid (Spanish for Caja Madrid Tower), with a height of 250 m, is the tallest of the four buildings in the complex, 89 cm higher than Torre de Cristal. It was first known as Torre Repsol and was to have served as headquarters for the oil and gas company Repsol YPF. During the construction of the tower, Repsol decided to change the location of its future headquarters, and the financial institution Caja Madrid purchased the building for €815 million in August 2007.
Designed by Cesar Pelli and built by Dragados, Torre de Cristal (Spanish for Crystal Tower), with a height of 249.5 meters, ranks as the second tallest building in the country after Torre Caja Madrid. In April 2007, its structure surpassed the height of Torre Espacio, for a while becoming the tallest building and structure in Spain.
Designed by Carlos Rubio Carvajal and Enrique Álvarez-Sala Walter and built by Sacyr Sau, the 52-storey skyscraper Torre PwC, formerly known as Torre Sacyr Vallehermoso, is 236 meters (774 feet) tall.
