The Pearl of the Adriatic became a major Mediterranean power after the 13th century. This late-medieval planned city in the south part of the east Adriatic Croatian coast with its historical core situated at the foot of Mount Srđ has preserved the character of a unique urban whole throughout the centuries, defined by the city walls. It has a significant place in the history of city planning. Although severely devastated by the 1667 earthquake, Dubrovnik has managed to preserve its gothic, renaissance and baroque churches, monasteries and fountains.
