The exact site was re-discovered in 1766 by the English antiquarian Richard Chandler. The first excavation of the sanctuary at Olympia was not carried out until 1829, by the French "Expedition Scientifique de Moree".

Since the 1870s, the excavation and preservation of Ancient Olympia has been the responsibility of the German Archaeological Institute at Athens. The first major excavation of Olympia began in 1875, funded by the German government after negotiation of exclusive access by Ernst Curtius.

The finds were displayed in a museum on the site.1900-1950.
Excavation was continued in a more limited way by Dörpfeld between 1908 and 1929 but a new systematic excavation was begun in 1936 on the occasion of the 1936 Summer Olympics in Berlin under Emil Kunze and Hans Schleif. Their excavation focus was on the area to the south of the stadium, the South stoa, bath complex and gymnasion.1950 to present
Between 1952 and 1966, Kunze and Schleif continued the excavation joined by architect Alfred Mallwitz. They excavated Pheidias' workshop, the Leonidaion and the north wall of the stadium. They also excavated the southeast section of the sanctuary and out of
