Acropolis of Agios Andreas, Sifnos: A Mycenaean acropolis overlooking the Aegean Sea

Excavations have uncovered most of the acropolis, along with its complex Mycenaean defensive system. Evidence so far indicates that the site was already occupied during the Late Neolithic/Early Bronze Age (late 4th millennium BC). The Mycenaean acropolis appears to have been abandoned in the 11th century BC and was reoccupied during the historical period, in the second half of the 8th century BC.

Apart from the panoramic view of the central settlements of the island and the Aegean Sea itself, what makes the site worth visiting is the Mycenaean wall, an outstanding example of an ancient fortified acropolis, unique in the region. It features eight rectangular towers enclosing the remains of several buildings dating to the Mycenaean and Geometric periods, some of which continued to be occupied until the Hellenistic period – albeit with modifications.

Sanctuary (Building F), enclosed within a monumental rectangular precinct wall constructed during the Archaic period, stands out among them.
