Holy Cross Church (Nin): Holy Cross is the oldest church in Croatia and also the world's smallest cathedral, according to signs posted outside. According to one scientist, the little white stone church is also a giant sun dial and was constructed according to mathematical calculations.
Euphrasian Basilica Complex (Porec): A must-see sight in this city of superlatives, the UNESCO World Heritage church is the final of four that were built on top of each other. One of its premier attractions is the collection of Byzantine mosaics on display. This is not just one church, but a series of church buildings, each with its own story.
St. Donatus (Zadar): Notable for its unusual shape (circular inside), St. Donatus has a dearth of decoration. The church is no longer used for Mass, but its great acoustics make it a hot venue for classical concerts. Like other churches of its time (9th c.), Donatus is one of several buildings in a clerical complex.
Church of St. Mary (Beram): This chapel in the woods is so small and so remote that you would never notice it if it weren't in a guidebook. But its very remoteness is what protected the eye-popping frescoes that dance on St. Mary's walls. You'll need to pick up one of the church's keepers in Beram and drive to the chapel in the woods so she can unlock it, but it's worth it.
