The Walls of Padua (Italian: cinta muraria di Padova) are a complex of defensive works around the Italian city of Padua, designed to defend it from hostile attack. It was built in 4 phases.Of the walls built during the ancient Roman era, the only traces to survive are those incorporated into the foundations of certain palazzi. The route of this wall corresponded to a meander of the river Medoacus (now the Brenta River) in which developed Padua's first urban centre.The Mura Duecentesche ("13th century walls"; also known as the mura comunali or mura medievali) were built at the start of the 13th century by the Comune of Padua. Their route was delimited by the two branches of the Bacchiglione, the Tronco Maestro and the Naviglio Interno, which came to be used as defensive ditches. There are several remains of them around the Castello and near Porta Molino.
