The Stoa of Attalos was a grand stoa (covered walkway) in the ancient Agora of Athens, built by King Attalos II of Pergamon between 159 and 138 BC[1]. It was reconstructed from 1952 to 1956 by the American School of Classical Studies at Athens[2]. Today, it houses the Museum of the Ancient Agora[2].
