Monument of Agrippa, Ancient pedestal near Propylaea in Athens, Greece

The Monument of Agrippa is an ancient pedestal on the western side of the Acropolis, built from different types of marble. The structure features a tall shaft made of bluish-grey Hymettian marble with a base and crown of white Pentelic marble.

The pedestal was built in 178 BC for Eumenes II of Pergamon to mark his chariot-race victory at the Panathenaic Games, and it held a bronze quadriga with Eumenes and his brother Attalus II. Around 27 BC the city of Athens replaced that group with a quadriga of Marcus Agrippa, son-in-law of Augustus, honouring his reconstruction of the Odeon. Only the pedestal survives.

The monument's west face carries a Greek inscription naming Marcus Agrippa as the city's benefactor, son of Lucius and three-time consul. Beneath it, traces of an earlier inscription are still visible, showing that the pedestal was reused. The bronze chariot groups that once stood on top are gone; only the base remains.

The monument sits directly on the main path through the archaeological site and is easy to reach when visiting the Propylaea. The pedestal is accessible from all sides and can be viewed up close without any special arrangements.

The monument leans noticeably to one side and no longer stands perfectly vertical, a tilt documented by measurements since the late 19th century. This lean is visible to the naked eye during a visit and shows how even massive stone structures change over time.
