St. Mary’s City, MD – Help uncover the past at Historic St. Mary’s City — Tidewater Archaeology Days are July 25 and 26!  

Tour excavations at the home of Maryland’s first governor.  Discover what the soil reveals about Maryland’s beginnings then help screen excavated material and see what bits of the past you recover.   Archaeologists will help you interpret the stories of the past that each piece tells.   An exhibit of artifacts recovered from the site will be on display.
