Silbury Hill for International Archaeology Day

Each year, International Archaeology Day—observed on the third Saturday of October—invites us to literally look beneath the surface. Established in 2011 by the Archaeological Institute of America (AIA), it"s celebrated worldwide through events, tours, and hands-on excavations.
