Fodor's Expert Review Crkva Svetoga Križa

Croatia's oldest church, the 8th-century Crkva svetog Križa is also known locally as the "world's smallest cathedral." Indeed, the simple, three-naved whitewashed structure—which has a solid cylindrical top and a few tall Romanesque windows (too high to peek inside)—has an unmistakable monumental quality to it even though it's no larger than a small house. There's little to see inside, though it is sometimes open, erratically, in summer; check with the tourist office or the Archaeological Museum.
