Matthys Levy and Mario Salvadori offer a fascinating account of architectural and engineering disasters throughout history. From the pyramids of Egypt and the Hagia Sophia to St. Mark's Campanile in Venice, and finally to the Empire State Building and the Twin Towers, the authors take us on a marvelous journey through the technology, genius, bad luck, and, of course, tragedy that have shaped the history of architecture.
Using practical language while still incorporating the necessary technicalities of the subject, Why Buildings Fall Down is a book that seeks to explain the structural behavior and lifespan of man-made buildings, clarifying how external environmental factors, use, and construction planning affect their durability and strength.

Throughout the book, which is available for purchase on Amazon, the authors recount in detail a series of disasters related to emblematic constructions that have occurred in the history of humanity, from pyramids and basilicas, concluding with recent disasters such as the Twin Towers where a series of elements combined to cause the collapse of these structures, wanting to raise awareness how even with advances in construction techniques, planning and sometimes luck are necessary to prevent these situations from occurring.
