Urbis Occultae Exploratoris Speleology is the scientific study of caves and other karst features, their make-up, structure, physical properties and history. Milan’s underground, as many other italian ones, is full of sewage pipes, tunnels, military bases, crypts, churches and loads of forgotten works. Brothers Davide and Gianluca Padovan, explorers and speleologists from Milan brought all of this back to light. They’re bound by a strong passion for speleology, which they’ve been practising with an innovative spin. Instead of looking for mountain caves, they focus on urban ones, giving life to the so called S.C.A.M ( Artificial Cavity Speleology Milan).
