Visit one of the old monasteries and take a walk on the city walls
Dubrovnik's Old Town has been a UNESCO World Heritage Site since 1997. It is bordered by historic city walls and cars are not welcome there. You enter through one of three entrance gates: Pile (main gate on the west side), Ploče (on the east side) and Buža (on the north side). Once in the Old Town, you enter a maze of streets, alleys and stairs. Just outside the city walls is the old port.
