The Stoa of Attalos (also spelled Attalus) was a stoa (covered walkway or portico) in the Agora of Athens, Greece. It was built by and named after King Attalos II of Pergamon, who ruled between 159 BC and 138 BC. The current building was reconstructed from 1952 to 1956 by the American School of Classical Studies at Athens and currently houses the Museum of the Ancient Agora. Description Typical of the Hellenistic age, the stoa was more elaborate and larger than the earlier buildings of ancient Athens and had two rather than the normal one storeys. The stoa's dimensions are and it is made of Pentelic marble and limestone. The building skillfully makes use of different architectural orders. The Doric order was used for the exterior colonnade on the ground floor with Ionic for the interior colonnade. This combination had been used in stoas since the Classical period and was by Hellenistic times quite common. On the first floor of the building, the exterior colonnade was Ionic and the interior Pergamene. Each story had two aisles and twenty-one rooms lining the western wall. The rooms of both stories were lighted and vented through doorways and small windows located on the back wall. There were stairways leading up to the second story at each end of the stoa. The building is similar in its basic design to the Stoa that Attalos' brother, and predecessor as king, Eumenes II, had erected on the south slope of the Acropolis next to the Theatre of Dionysus. The main difference is that Attalos' stoa had a row of 42 closed rooms at the rear on the ground floor which served as shops. The spacious colonnades were used as a covered promenade. History A dedicatory inscription engraved on the architrave states that it was built by Attalos II, who was ruler of Pergamon. The stoa was a gift to the city of Athens for the education that Attalos received there under the philosopher Carneades. His elder brother and his father had previously made substantial gifts to the city. The building was constructed on the east side of the Agora or market place of Athens and was used from approximately 150 B.C. onwards for a variety of purposes. The stoa was in frequent use until its woodwork was burned by the Heruli in AD 267. The ruins became part of a fortification wall, which made it easily
