Greece's sightseeing is layered in a way that archaeologists, historians, and casual visitors all experience differently from each other. The ancient sites, the Byzantine churches, the Ottoman and neoclassical layers at street level in the old quarters — each era leaves its own legible trace. The great antiquity collections require a full half-day of serious attention. The islands add entirely separate registers: Minoan palace archaeology, Hellenistic urbanism, Bronze Age fresco, medieval Venetian fortifications. The country rewards lateral movement through regions and periods equally. Tours by locals often make the place feel warmer, sharper, and more personal. It really hits differently.
