In August, the night of the full moon sees various archaeological sites throughout the country staying open until 1:30am with free admission. Regular participants include the Acropolis in Athens, as well as places such as Ancient Olympia and Ancient Corinth on the Peloponnese, Delos archaeological site (on the tiny uninhabited island close to Mykonos), and Edessa archaeological site in the Greek region of Macedonia. Concerts are also scheduled at some venues.
