The Archaeological Society of Athens (Εν Αθήναις Αρχαιολογική Εταιρεία) is a branch of the Hellenic Republic's Ministry of Foreign Affairs. Also termed the Greek Archaeological Society, it was founded in 1837, just a few years after the establishment of the Greek State, with the aim of encouraging archaeological excavations, maintenance, care and exhibition of antiquities in Greece.
Preserved are the unusual theatre of the 6th-4th centuries B.C., parts of the settlement, some of the metal-working establishments, a square tower of the 4th century B.C., the cemeteries and the sanctuary of Demeter and Kore.
The Agora was the heart of ancient Athens, the focus of political, commercial, administrative and social activity, the religious and cultural centre, and the seat of justice.
Archaeological evidence shows that there was a sanctuary here from the beginning of the 6th century B.C. The archaic temple was destroyed by the Persians in the attack of 480-479 B.C., as were many other buildings in Attica.
