Santorini may very well be the most famous of the Greek islands, and its capital, Fira, is a vision of pristine whitewashed buildings built into dramatic, rugged cliffs that slope into the sea. The Archaeological Museum Fira contains Minoan artifacts from Fira’s ancient-world beginnings, while several churches and monasteries offer a glimpse into the religious makeup, both historical and contemporary, of this postcard-perfect village. Exploring the shops and cafes along narrow footpaths, and taking in the truly amazing views, is a leisurely way to spend an afternoon.
