The Tombs of Marathon, 42 kilometres from Athens, are the burial mounds of the brave Athenian and Plataean heroes who gave their lives during the battle of Marathon in 490 BC, where their heavily outnumbered army defeated the mighty Persians. There are three monuments of the plain of Marathon, the Athenian Tumulus, the Plataean Tumulus, and a victory column erected by the Athenians.
