The Offering of Marathon was erected after the Athenian's famed victory at the Battle of Marathon. Thirteen statues, including Athena, Apollo, General Miltiades, and various other heroes of the battle. Later, three additional statues were added of the kings Antigonos, Demetrios Poliorketes, and Ptolemy.

On either side of the road stand the semi-circular exedrae of the Argive Dedications. To the left stands the monument of the Epigones, commemorating the descendants of the generals from the first Argive invasion of Thebes. These Epigoni shared their ancestors success by launching a second, victorious invasion against Thebes. On the right, made in 456 BC after the Argive triumph over the Lacedaimonians, stands the other exedrae, which is dedicated to the original Argive generals who invaded Thebes.
