It is time once again for The National Museum of Civil War Medicine to offer visitors a chance to tour the most haunted building in Frederick, Maryland.

During the month of October, Museum staff and volunteers will share stories of Civil War embalmers, the building’s most infamous tenants, and their first-hand accounts of paranormal activity that has given the building its creepy reputation. In addition to a trip through the museum galleries, the tour provides exclusive access to the third floor where numerous sightings have occurred.

Visitors are encouraged to bring their own cameras and ghost-finding apps to capture possible paranormal activities.

Tour dates are Oct. 14, 21, 28 and 29 from 5-6:30PM. There is also an "extra spooky" tour for adults 21 and over on Oct. 28 at 7PM (with a tasting of Letterman Lager included).
