Perched on Adriatic Sea in Croatia, Zadar is a truly captivating city, where history-drenched cobblestone streets meet contemporary life, then surrounded by deep blue sea, green olive groves, and white stone. Dubbed an “outdoor museum”, Zadar is rich in monuments and churches from ancient and medieval times—the circular 9th century Church St. Donat, the Church of St. Simeon and the Romanesque Cathedral of St. Anastasia—while nature lovers should explore Krka National Park and its seven waterfalls. Meander through the pedestrian-only Old Town, with its fortified city walls, towers and gates, then visit Zadar’s famous urban installations on the Riva, where art, architecture and science combine. Be sure to check out The Sea Organ, which extends into the sea and “whistles” with the waves and air pressure, and Greeting to the Sun, a circular construction of glass plates that produces an exceptional light show.
