Dubrovnik, a city in southern Croatia along the Adriatic Sea, is famous for its distinctive Old Town, surrounded by massive stone walls dating back to the 16th century. The city's well-preserved architecture includes the Baroque St. Blaise Church, the Renaissance Sponza Palace, and the Gothic Rector’s Palace, now a history museum. The pedestrian-friendly Stradun (or Placa), paved with limestone, is lined with shops and restaurants.
