A brisk fall chill wasn’t the only thing in the eerie air of the Fearing Tavern late Saturday night.

The evening’s blustery weather provided the perfect backdrop for a group of 11 brave souls to join three paranormal investigators on a hunt for spirits through four of Wareham’s historical buildings.

The program, meant to benefit the Wareham Historical Society, was called “Ghosts of Gateway,” and focused on the Fearing Tavern, built in 1690; the Old Meetinghouse, built in 1835; the One-Room Schoolhouse, built in 1825; and the Union Chapel, built in 1880.

Though investigators Tim Weisberg and Matt Moniz focused primarily on the Fearing Tavern, investigator Andrew Lake remained on hand at the Meetinghouse for attendees who wished to go elsewhere. Participants were also invited to explore the Union Chapel and the Schoolhouse on their own, and Wareham Historical Society members were on hand in each area to discuss the history of the buildings.

Weisberg, who began ghost hunting in late 2005, is a sports journalist for the Standard-Times. He opened the night’s investigation with a discussion in the Meetinghouse regarding the nature of ghosts, and tales from some of the investigations he had done. Though popular culture would believe ghosts are the actual souls of the deceased, Weisberg presented some other theories, among them the quantum theory-based idea that ghosts are results of ‘slips’ between parallel universes, or slips in time.

“With the idea of quantum reality, there are multiple other universes,” Weisberg said. “There’s other universes that exist on top of this universe. … Once in a while, they roll into each other. They’re ghosts to us. Maybe we’re ghosts to them.”

Weisberg explained that the South Coast is allegedly among the most haunted areas of Massachusetts, owing, in part, to King Philip’s War, the biggest conflict of 17th century Puritan New England.

“The whole South Coast is one big battlefield where this war was fought,” Weisberg said. “Every time [people] build something … they end up digging up these cemeteries they didn’t know existed.”

The Spooky Southcoast group was the first to investigate the Fearing Tavern. Weisberg said the place lit up with ghostly activity, including a rather chilling encounter in the basement, and a strange, faerie-like light captured on video zipping through the doll room, which he played for the group.

“You’ll see kind of like a little fluttery, white light come in,” Weisberg said of the video, which he mentioned is available to view online.

The entire investigation of the buildings lasted from 8:30 p.m. Saturday to 1 a.m. Sunday. Some of the participants used dowsing rods to talk to any potentially ghostly presences, while others followed Weisberg, who used equipment meant to capture electronic voice phenomena, and other devices to pick up any spiritual activity.

And is the Fearing Tavern haunted? Well, this journalist knows what she saw, but leaves it up to you, dear reader, to find out.
