The Intempo in Benidorm, Spain,
The building consists of two parallel towers separated by a gap of 20 metres and connected by a cone-shaped structure between floors 38 and 44. Its frontal view, vaguely resembling the number 11 and the letter M, has led commentators to speculate about a possible reference to the terrorist attacks of 11 March 2004 in Madrid. It is one of the few skyscrapers in the world which has the shape of an arch (another in Europe being the Grande Arche in Paris).
