The Herakleidon Museum is a non-profit cultural organization founded in 2004 by Paul and Anna-Belinda Firos. It consists of two buildings in the historic district of Thissio, next to the Acropolis, the Ancient Agora and the Temple of Hephaestus. The first building is located at 16 Herakleidon street, and the second one is 150 meters further, at 37 Ap. Pavlou street, one of the busiest pedestrian streets in Athens.
