Had such a Ripley’s Believe It or Not moment when seeing The Leaning Tower of Pisa. Crazy but, apparently all the buildings of the Campo dei Miracoli lean because of their shallow foundations and sandy silt subsoil. Surreal! Prior to restoration work performed between 1990 and 2001, the tower leaned at an angle of 5.5 degrees, but the tower now leans at about 3.99 degrees. This means that the top of the tower is displaced horizontally 3.9 meters from where it would be if the structure were perfectly vertical!
