"The Acropolis of Athens is one of the most important historic sites in the world. It includes a number of ancient buildings including the famous Parthenon, a temple devoted to the Greek goddess Athena. Because of excavations and renovations, portions of the Acropolis are often closed to the public. However, there are rumors that these renovations are a cover for a secret organization with a hidden stronghold somewhere on the site. Nothing has been confirmed, but visitors have reported hearing strange noises late at night."
