Tumulus of Marathon, Athens Greece

This historic location is the site of the battle of Marathon in 490 BC, in which the heavily outnumbered Athenians defeated the Persians.   The Tumulus, or burial mount, was the last resting place of the 192 Athenians who fought there.   It is also the starting point of the Marathon race, held annually in memory of the messenger Phidippides, who ran the 42 km (26 miles) from Marathon to Athens to announce the victory.   Exhausted, Phidippides died soon thereafter.
