These days, one of the world’s oldest cities is brimming with new life. See the Acropolis and the Ancient Agora, sure, but don’t missing shopping Monastiraki’s flea market, walking up Lykavittos Hill, or exploring the city’s burgeoning Exarcheia neighborhood. Earmark an afternoon for the Renzo Piano-designed, $623 million Stavros Niarchos Foundation Cultural Center, which houses the National Opera and the National Library of Greece, and sits on the biggest park in Athens. When you’ve had your fill of touring, fuel up with a souvlaki (or three) at O Kostas, which serves the best in town.
