Zagreb developed from two medieval cities with hilltop fortifications overlooking the Sava River and was reborn in the Baroque period as a business center, conveniently located on the routes that connected Central Europe and the Adriatic Sea. Today, Zagreb is the heart of contemporary Croatian culture, art, sport, and science, but its history is not forgotten. A unique combination of medieval towers, 19th-century palaces, open-air markets, and a magnificent cathedral make Zagreb a perfect city for exploration.
