The impressive Stoa of Attalos is a restored building on the eastern side of the Ancient Agora.

Named after King Attalus II of Pergamon, who gave it to the city as a gift, the Stoa was erected between 159 and 138 BC. It was, at the time, the longest free-standing, roofed building in the city.

Designed to house the city’s commercial activities, the two-storey structure measured 120 metres long, and contained 21 stores and workshops. With walls constructed entirely of limestone, the doors, door jambs, staircases, columns and wall studs were all of white Pentelic marble.

Destroyed in the Herulian sack of Athens in 267 AC, the Stoa’s remnants were used to build the Roman wall. Rebuilt in the 1950s by the American Archaeological Institute, the Stoa rose again, this time to house the Museum of the Ancient Agora.
