The site of the Ancient Olympic Games in Olympia in the Peloponnese was lost to time and earthquake until 1875 when excavation began to uncover the ancient stadium (which could seat 20,000), the Temple of Zeus, the Temple of Hera (where the Olympic Flame is still lit from the sun), and many other important buildings.
Today they are only ruins, foundations and columns mainly but still of great interest and one of the most visited ancient sites in Greece.
Adjoining the site is the Archaeological Museum of Olympia, which contains some of Greece's most valuable historic artifacts found in the Altis or sanctuary to Zeus. The museum is famous for its sculpture collection including Nike who was said to come down from the sky to hand a palm leaf to the victors. The large terracotta collection is also renowned and this modern museum is a great way to get a feel for how it was to be at those ancient games.
