Megaestructuras: Sagrada Familia

Megastructures: Sagrada Familia is an inside look at one of the most clever and inspiring structures in Europe. The long life of its construction allows to show from traditional architectural construction techniques to the use of recent science and technology breakthroughs, including architectural 3D visualization. Sagrada Familia represents the harmony between the old and the new, between the constructors of medieval cathedrals and geniuses of postmodernism. (National Geographic)
