Mycenaean sanctuary
Mycenaean sanctuaries have been discovered in numerous Greek locations, mostly in areas that are either close to a significant settlement or to natural attractions.
Depending on the deity, a sanctuary was located in a specific place. Be it by the sea (Po-I-Tan / Poteido / Po - ti - To = Poseidon ) or near volcanoes, springs or forests. The sanctuaries were either graves of Mycenaean warlords / heroes (mostly domed graves or circular structures around graves) or were located in a megaron .
Famous sanctuaries were discovered in Mycenae ( Peloponnese ), Tiryns or Pylos . The shape of the megaron was the forerunner of the ancient temples .
The sanctuary discovered in Methana in 1990 with a sacrificial site from the period 1400–1200 BC. Chr. Is assigned to a prehistoric figure of Poseidon.
