Greek museums and archaeological sites across Attica are staying open late on Friday, August 28, 2026, to celebrate the August full moon with free events. The celebration is part of a nationwide program organized by the Hellenic Ministry of Culture for residents and visitors remaining in the capital region over the final weekend of the month.
Known traditionally as the Sturgeon Moon, the August full moon takes its name from Native American traditions associated with catching sturgeon fish in large quantities during this season. The Ministry of Culture has arranged activities at 126 archaeological sites, historical locations, monuments, and museums throughout Greece. A total of 61 locations are hosting scheduled cultural events, while another 65 sites are remaining open late into the evening with free admission so the public can view them under the moonlight.
The broader program of activities extends across the final days of August and features theatrical performances, concerts, dance shows, art exhibitions, and guided tours. In the capital region of Attica, three major museums are offering special Friday night programs, allowing visitors to experience ancient artifacts and live music under the night sky.
