• Mistra (Peloponnese): This Byzantine ghost town has streets lined with the remains of homes both humble and palatial, as well as some of the most beautiful churches in all of Greece. If you have the energy, climb to the top of the defense walls for the superb view over the plain of Sparta. Try to visit in spring, when Mistra is carpeted with wildflowers.
  • Church of Panagia Kera (Kritsa, Crete): Even if Byzantine art seems a bit stilted and remote, this striking chapel in the foothills of eastern Crete will reward you with its unexpected intimacy. The 14th- and 15th-century frescoes are not only stunning but depict many familiar biblical stories.
  • The Churches of Thessaloniki (Northern Greece): Thessaloniki's Byzantine churches are the finest not just in Greece but in the entire world. From tiny Osios David to towering Ayios Dimitrios, these churches boast mosaics and frescoes that give you astonishing glimpses of the artistic grandeur of the mighty Byzantine Empire.
  • Nea Moni (Hios, Northeastern Aegean): Once home to 1,000 monks, this 11th-century monastery high in the interior mountains of Hios is now inhabited by only a handful of monks and nuns. Try to catch one of the excellent tours sometimes offered by the monks. The mosaics in the cathedral dome are works of extraordinary power and beauty. Check out the small museum, and take some time to explore the monastery grounds.
  • Monemvassia (Peloponnese): Long called "the Gibraltar of Greece," this rocky promontory crowned by a medieval citadel and church has only one real street (just wide enough for two donkeys to pass each other), no cars, cobbled lanes, beautifully restored stone houses (some of which are now hotels), and views that stretch seemingly forever over the sea.
  • A Clutch of Castles: Acrocorinth, Argos, Methoni, Koroni, Mistra & Nafplion (Peloponnese): Some of these castles have ancient foundations; all were added onto by the Franks, Venetians, Byzantines, and Turks. Several were used as fortresses as recently as World War II; one, Koroni, has a convent and settlement within its walls.
  • A Profusion of Byzantine Churches in the Cyclades: The fertile countryside of the island of Naxos is dotted by well-preserved Byzantine chapels. Parikia, the capital of Paros, has the Byzantine-era cathedral of Panagia Ekatondapiliani. Santorini boasts the 11th- to 12th-century Church of the Panagia in the hamlet of Gonias Episkopi.
