A Panhellenic sanctuary was a sanctuary, shrine or place of worship in Ancient Greece, that was open to all Greeks regardless of the city-state it belonged to. These places were often the subject of pilgrimages from all the Greek world.
Normally, a sanctuary or shrine belonged to the city in which territory it was situated. Panhellenic sanctuaries were places of neutrality, and were therefore used as neutral places of political meetings between different Greek city-states, places where Panhellenic Games were held, and well as places were different Greek powers could keep their treasuries.[1]
