The sanctuary of Dodona (Dodoni) was the most important religious centre of northwestern Greece and one of the oldest sacred sites in the ancient Greek world, closely associated with the worship of Zeus, father of the gods, and Dione, an ancient mother-goddess figure. Dodoni was especially famous for its oracle, traditionally regarded as the oldest in Greece and already mentioned by Homer in the Iliad and the Odyssey, underscoring its significance in the early Greek religious imagination.
Archaeological evidence shows that the site was already a place of worship in the late Bronze Age (Mycenaean period, around the 2nd millennium BCE), long before the rise of the classical Greek city-states. It gradually developed into a major Panhellenic sanctuary, attracting visitors and offerings from across the Greek world, including Epirus, Thessaly, and the wider Mediterranean. The sacred oak tree (hiera drus) stood at the heart of the sanctuary, believed to be the living channel through which Zeus communicated his will.
The oracles were interpreted through the rustling of the sacred oak leaves, the murmuring of a nearby spring, and the sound produced by bronze cauldrons placed on tripods around the sanctuary. These cauldrons, when struck or moved by the wind, produced a continuous ringing sound believed to carry divine messages. Over time, more structured forms of divination also developed, including the interpretation of written questions and answers on lead tablets discovered by archaeologists.
According to ancient sources, the priests of the oracle were originally men, but later priestesses, known as the Peleiades (“doves”), became central to the cult. Both priests and priestesses were said to live in close connection with nature, often walking barefoot and sleeping on the ground as a form of ritual purity and spiritual alignment with the earth.
In addition to its religious role, Dodoni also had political and cultural importance. City-states and rulers from across the Greek world consulted the oracle on matters of war, colonisation, and public policy, making it a key institution in ancient decision-making. The sanctuary flourished particularly during the classical and Hellenistic periods, when monumental temples, theatres, and stoas were constructed.
