Stoa of Attalos

Τhe Stoa of Attalos, built during the reign of Attalos II of Pergamon (159–138 B.C.), who studied in Athens under the philosopher Karneades before becoming king. The stoa served as the main commercial center for the Athenians for centuries; it was destroyed by the Herulians in A.D. 267 and then incorporated into the new fortification wall, which preserved its northern end up to roof level. It was fully restored in 1953–1956 to serve as the site museum.
