This archeological site is still quite intact. Well, the outlines at least are (not the buildings). At the center is the Zeus temple. Around it is the residence of priests, the training rooms facilities for the athletes, the guesthouses.
Via a passageway, called the Crypt, you reach the stadium. The place where the athletic games were held measured 212 x 28 meters. There were no seats, but the embankment could hold 45.000 spectators.
In the nearby museum, you can see a model of how Olympia looked like at its heydays. An amazing, bustling site it must have been: think of the athletes practicing, but also the numerous spectators and officials that were around. Not unlike an Olympic Village nowadays, but on such small grounds.
