Ancient Agora. Athens. Greece. View of part of the late Roman defensive wall that lines the Panathenaic Way on the eastern side of the Agora. The wall was built in the 3rd century AD after the Herulians invasion in 267 AD. The wall is made of remains of destroyed buildings, including Ionic and Doric columns, architrave blocks, inscriptions, and statue bases. The Agora from 600 BC onwards was the commercial and social centre of Ancient Athens. It was here that laws were written and displayed, commercial goods bought and sold, intellectual discussions were had, and the democratic spirited was born and nurtured.
