Plaza Guest House

The Plaza Guest House stands in Provincetown, Massachusetts, constructed in 1850 during the nineteenth century as the town developed its character as a maritime center and increasingly as a residential and artistic community drawing visitors from throughout the Northeast. The building was engineered and constructed to serve as a guest house and inn, providing lodging for visitors to the Cape Cod peninsula's growing population of travelers and seasonal residents. The architecture reflects the period in which it was built, with design elements and construction techniques typical of mid-nineteenth century New England residential hospitality establishments. The structure has been preserved and operated as a guest house across more than 170 years of continuous use, serving multiple generations of visitors while simultaneously hosting paranormal presences anchored to historical traumas and criminal violence perpetrated within its walls during the late twentieth century.

Paranormal phenomena trace directly to the criminal actions of serial killer Tony Costa, a Provincetown resident who committed horrific murders during the late 1960s and early 1970s, a period when his violent crimes terrorized the community and devastated families of multiple young female victims. Costa's connection to the Plaza Guest House created permanent association between location and violence. The victims have apparently remained spiritually anchored to the location where they suffered and died, creating concentrated paranormal manifestation driven by the trauma and violence of their deaths. The specific pain, fear, and violation experienced appears to have created an imprint upon the building itself, persisting despite the structure's continued operation.

Room 006 has become the most intensely haunted space within the Plaza Guest House, with paranormal phenomena concentrated within this particular guest accommodation. The room is characterized by persistent reappearance of bloodstains on surfaces despite repeated cleaning and removal, suggesting manifestation at spiritual or energetic level rather than physical mechanisms. Room 4 similarly bears paranormal weight, associated with documented presence of victims and characterized by disembodied voices including primal screams and terrified whimpers. Auditory phenomena convey the emotional and physical anguish experienced by victims, their voices persisting beyond death as expressions of unresolved trauma.

Manifestations throughout the Plaza Guest House reflect presence of multiple distinct entities associated with Costa's victims. Apparitions dressed in period clothing consistent with late 1960s and early 1970s fashion appear in solid or translucent form throughout rooms and hallways. Objects are documented as being thrown at guests without visible agency or explanation, suggesting defensive or aggressive manifestations. Doors open and close with apparent responsiveness. A glowing apparition has been reported chasing guests, suggesting distinct spiritual presence or greater intensity than companions. The scent of blood is reported by multiple witnesses, concentrated in Room 006, persisting despite thorough cleaning and environmental controls.

The cumulative weight of these phenomena—visual apparitions, auditory manifestations, olfactory phenomena, physical contact, and reappearing bloodstains—creates a location of intense paranormal activity reflecting the violence and tragedy embedded in its history. The Plaza Guest House has become a focus of paranormal investigation and study, with documented activity contributing substantially to understanding how criminal violence and severe trauma create persistent supernatural manifestations. The building continues operating as a guest house with management and staff acknowledging the dark history and continuing supernatural presence characterizing this location.
