The Stoa of Attalus, in the ancient Agora of Athens, was a donation by the King of Pergamon, Attalus II (159 BCE – 138 BCE) to the city of Athens. It was two-storied, of Doric order, and was 115 metres long. It had 42 rooms that were used as shops. In north and south ends, staircases led to the second floor.
The Stoa was destroyed by the invasion of the Heruli in 267 AD. It was completely restored between 1953-1956 by the American School of Classical Studies at Athens, in order to house the Museum of the Ancient Agora.
