The Plaka is the “old” section of Athens, under the Acropolis. “Old” is a relative term in a city that goes back millennia. In this case, “old” means “before the automobile.” The Plaka is closed to the automobile traffic that clogs most of Athens, making it pleasant for exploration on foot (although motorcycles and the small delivery vehicle in this picture are permitted). It’s a district that caters to tourists, with restaurants, shops, and cafes. When I took this picture it was also the nightclub and taverna district; the government subsequently banished those unsavory establishments.
