The Stoa Poikile, also known as the Painted Porch, was an important public building in the Ancient Agora of Athens, dating back to the 5th century BC. Famous for its murals depicting historical and mythological feats – the work of artists such as Polygnotus – it gave its name to the Stoic school of philosophy, founded by Zeno of Citium who often taught there. In addition to its artistic and philosophical value, the stoa housed war trophies in the form of shields and was a meeting place for philosophers, beggars, and street performers. Its foundations, discovered in the 1980s, reveal a building of notable dimensions combining Doric and Ionic styles.Wikipedia
