Stoa Poikile
Athens Municipality, Greece
The Stoa Poikile (Ancient ἡ, hē poikílē stoá) or Painted Portico was a Doric stoa (a covered walkway or portico) erected around 460 BC on the north side of the Ancient Agora of Athens. It was one of the most famous sites in ancient Athens, owing its fame to the paintings and war-booty displayed within it and to its association with ancient Greek philosophy, especially Stoicism.
