On our trip to Athens last year I took notice of the orange trees planted along public roadways. Not just in a few spots, but all over the city. Oranges were ripe and some were already on the ground. Oftentimes the orange trees were between sidewalk and building front or even sidewalk and road. Kinda cool to have an available snack at the ready any time they're ripe. Though with the minimal exhaust standards, not sure I'd find the oranges as tasty as rural, tropically-grown oranges.
The last photo below was taken over the fence at the new Acropolis Museum, just down the hill from the Parthenon. Inside the wall they were growing -- you guessed it -- orange trees. What museum grows and orchard?
