Brindisi is an Apulian port city on the Adriatic. The Alfonsino Castle in red stone stands on an island at the entrance to the port. The imposing Monument to the Sailor of Italy in limestone shaped rudder gives views of the sea and the city. On the other side of the port, the Swabian Castle dates back to the '200. At the top of the Staircase Virgiliana, instead, stand the Roman Columns.
