Entering from the Filarete Tower, one walks into the vast Courtyard of Arms, extensively restored by the architect, Luca Beltrami. On the side facing the Carmine gate, stand the remnants of a by-gone age: stone sarcophagi from the late Roman period (3rd - 4th century AD), fragments of statues and archaeological artefacts. Façades that decorated two buildings on what today are via Bassano Porrone and via Spadari, in central Milan, have been attached to the courtyard wall. On the opposite side of the courtyard is the Spanish hospital, while, moving towards the Ducal courtyard one comes upon the moat surrounding the medieval walls, known as the dead moat. Before reaching the moat one passes the 18th century white marble statue of Saint John Nepomucene.
