The values of fair competition and Sacred Truce, which were established during the ancient Olympic Games, are diachronic and always pertinent. The visitor of today, when visiting the archaeological site of Olympia, can feel the spirituality and ideological weight of this Olympian landscape. The sanctuary of Olympia and its surrounding landscape has been designated as an archaeological site (Government Gazettes 128/B and 216/B of 1992). The archaeological site of Olympia is protected at all times. The dikes that have been constructed along the banks of Alpheios river, south of the sanctuary, protect the archaeological site effectively from the river’s flooding phenomena.
