About Acropolis of Athens

The Propylaea gateway, the Erechtheion with its Caryatid porch, and the Temple of Athena Nike stand within the same walls, and the Acropolis Museum at the base holds the finds from the excavated slopes. April through June gives mild mornings for the climb and enough daylight for the museum afterward; July and August turn the marble into a reflector by mid-morning. Enter at opening, then retreat to Plaka's shade for the afternoon.
