We were in Madrid last weekend and saw the Puerta de Europa (‘Gateway to Europe’) towers, the world’s first leaning high-rise buildings. They were built in 1996 and designed by the American architects Philip Johnson and John Burgee. Each building is 115 m tall, or 26 stories, with an inclination of 15º, or more than twice that of the ‘leaning’ (pfft) tower of Pisa.
The buildings were very impressive. We visited them on our Madrid Vision tour; we got out at the Estadio Santiago Bernabeu of soccer team Real Madrid (stop 7 on the blue line) and walked in about 30 minutes from Plaza de Lima to Plaza de Castilla.
