Why does the Erechtheion differ from any other ancient temple? Why did the Athenians consider it to be the most sacred building on the Acropolis? This film presents all those features that make the Erechtheion unique, beginning with the age-old cults of gods and heroes that it housed and reaching down to its inventive architecture and outstanding sculptural decoration. It is a short story of the temple that was adorned with the Caryatids and stood in the very same place which received the worship of Athena, the protectress of the city. This is where the Athenians uninterruptedly ascertained their identity.
