Nestled in the town square of Concord, Massachusetts, the windows of the Colonial Inn have gazed upon more than three centuries of bloodstained history.

Known for its role in the American Revolution, the Inn was originally built as three separate buildings with the oldest section of the property dating back to 1716. A stone's throw from Old North Bridge, the Inn is notoriously haunted by the ghosts from its Revolutionary War past. Guests report phantom footsteps, disembodied voices, and spirited soldiers lurking in the shadows of the labyrinthine hallways and empty rooms of this infamous inn.

Local author Sam Baltrusis has worked the graveyard shift at Concord's Colonial Inn trying to unravel the chilling mysteries and lingering legends associated with one of the country's oldest and most haunted hotels.
