Croatia: Dubrovnik, in southeastern Croatia is situated on the southern Adriatic Sea coast with its fortifications rising directly from the water’s edge with a massive round tower that dominates the city. Dubrovnik was incorporated into Yugoslavia in 1918 and many of Dubrovnik’s historic buildings suffered damage in 1991–92 during Croatia’s struggle for independence, but much of the old city has since been restored. The city walls are a source of pride for Dubrovnik. The 6,365 feet long walls encircle the city and were erected in the 16th century. The Stradun, or main street, is lined with beautiful late-Renaissance houses on each side. No motor vehicles are allowed inside the walls, and, except for the Stradun, the old city is a maze of picturesque narrow streets, many of them steep and twisting.
