Greece's Ministry of Culture is organizing its 27th consecutive August full moon festival, offering free entry to the public at archaeological sites, monuments, and museums nationwide. The lunar event reaches its peak in the early morning hours of August 28, 2026, at 00:18 Greek time, but festivities will take place during the evening of Friday, August 28. A total of 126 venues will participate with open doors and no admission charges. While many locations will allow walk-in visitors, some sites require advance reservations for guided tours and special programming. The initiative aims to make Greece's rich cultural heritage accessible to residents and visitors during the summer season.
