The great thing is the photo itself, which was taken by photographer Miguel Sandoval Díaz, an incredible shot–the extended exposure time allows for shadowy, mobile traffic at the bottom right (although that is slightly covered up in the layout). If interested in his photography (I believe he is based in Madrid), he has volunteered his email (email@example.com) as contact information.
This photo shows the building(s) while still under construction–an essay by Malcolm Compitello notes “the original plan for the building dates from the mid-1980s. The architectural design was entrusted to the architectural firm of Burgee, Johnson and Associates known for their design of large buildings. Perhaps their most famous and controversial work is the firm’s initial entry into the realm of the grand postmodern, the AT&T Tower in New York. The elaboration of the plan for the work, the first inclined high-rise towers ever designed, was entrusted to Leslie E. Robertson and Associates. LERA is the New York-based structural engineering firm that has engineered the majority of the world’s tallest buildings, including the Torres Picasso in Madrid.”
See the original article here, and the building also plays a central role in the film El día de la bestia/The Day of the Beast (1995) by Spanish director Álex de la Iglesia. (a great cult classic)
