The Colonial Inn embraces the mystery, even including a "Haunted Inn" section on its website, which includes links to media coverage and investigations into the room, like the one from SyFy's Ghost Hunters that you can see above.
But the Colonial Inn isn't the only site with ghost stories in this town of Revolutionary and literary lore.
Another popular local ghost story features the "Skull Tombstone" at Old Hill Cemetery. According to the lore, there's an eerie aura throughout the 1700s burying ground, but the spookiest site is an old tombstone with strange skull image and equally unsettling “bowing to the king of terror” inscription. Some report seeing "real" eyes inside the skull's sockets, which appear to follow visitors as they move around.
We're sure these aren't the only Haunted Concord stories. If you've got one to share, add it to the comments section below!
