Archaeological Museum of Marathon, Archaeological museum in Marathon, Greece

The Archaeological Museum of Marathon opened in 1975 in Marathon, Attica, and occupies five rooms plus a roofed atrium. Its displays include finds from the Battle of Marathon, the Middle Bronze Age tumuli (2000–1600 BC) under a protective shelter, and the 5th-century BC tumulus of the Plataeans.

The museum opened in 1975 in Marathon, Attica, and grew around finds from the Battle of Marathon of 490 BC and from the Sanctuary of the Egyptian Gods at Brexiza, founded by Herodes Atticus in the 2nd century AD. Its five rooms and roofed atrium also hold the Middle Bronze Age tumuli cemetery of 2000–1600 BC and the so-called tumulus of the Plataeans from the 5th century BC.

Room 1 holds finds from the Pan Cave, dated 5300–3200 BC; in classical times the cave was a place of worship for the god Pan, who according to Herodotus protected the Athenians at the Battle of Marathon in 490 BC. Room 4 is dedicated to Herodes Atticus, a native of Marathon, and shows statues of him and his wife.

The museum sits about 5 kilometers from Marathonas town and is open daily except Mondays. The place has facilities for visitors with limited mobility, making a comfortable visit possible for everyone.

The museum shelters two burial grounds under a protective roof: a Middle Bronze Age tumulus cemetery of 2000–1600 BC and the so-called tumulus of the Plataeans from the 5th century BC, linked to the battle. Both stand outdoors beside the exhibition rooms.
