Ghost Frame Tours
March 21, 2026 | 11:00 a.m. & 1:00 p.m.
You see them on the landscape as you drive into Historic St. Mary’s City — tall wooden outlines standing quietly in open fields. But what are they?
Join a guided walking tour to explore our iconic “Ghost Frames,” which mark the locations of 17th-century buildings uncovered through archaeology. Discover what once stood here, who lived and worked in these spaces, and the stories hidden beneath the ground of Maryland’s first capital. These mysterious frames may seem simple, but they reveal a fascinating past waiting to be uncovered.
$5 per participant. Space is limited- registration required upon admission purchase.
