Zagreb

Zagreb needs 2 days: the Upper Town (Gornji Grad), with the twin-towered Gothic Cathedral and St. Mark's Church with its mosaic roof, on one, and the Museum of Broken Relationships, dedicated to objects donated by separated couples from around the world, on the other. April-June and September-October are best. It's inexpensive for Europe. Unlike Croatia's coastal image, it's a Central European capital of Austro-Hungarian tradition, with an intense outdoor café culture, and its Museum of Broken Relationships, winner of a European innovative museum award, became a unique cultural phenomenon with temporary venues in over twenty countries.
