Bridgewater Triangle
Roughly 200 square miles of southeastern Massachusetts named as a cluster of strange reports by one cryptozoologist in the late 1970s. The swamp at its center was called the place where spirits dwell long before he got there.
Field Guide Entry
The name is 45 years old, the reputation is not
Loren Coleman coined the Bridgewater Triangle in the late 1970s and published it in Mysterious America in 1983, drawing a rough triangle across southeastern Massachusetts and arguing that the density of odd reports inside it was not normal. The name stuck and the region has been marketed under it ever since.
The reports predate the label by centuries. The wetland at the center is the Hockomock Swamp, and Hockomock is Algonquian for the place where the spirits dwell. The area was the ground of King Philip's War in the 1670s, and Profile Rock is named in Wampanoag tradition as where Anawan received the wampum belt from Metacomet.
What is inside the triangle
The catalog is unusually varied for one region, which is Coleman's actual argument. Pukwudgies, small malevolent figures from Wampanoag tradition, are reported from the Freetown-Fall River State Forest. There are Bigfoot-type sightings, thunderbird reports, ball lightning, black dogs, and a run of unsolved cattle mutilations in the 1970s.
Freetown-Fall River State Forest carries a separate and entirely documented history of violent crime, which is bound up with its reputation and is a matter of court record rather than folklore.
The skeptical position
The individual reports mostly lack anything to examine. What the region has instead is unusual geography for the northeast: a large, difficult, poorly drained swamp that resisted settlement and stayed empty while everything around it filled in, bordered by towns with long memories.
A triangle drawn to include the strange reports will contain the strange reports. That is the standing objection to the whole framing, and it applies to every named triangle including the one off Bermuda.
Visiting Information
Hockomock Swamp is a state wildlife management area, open to the public for hiking, fishing, hunting, and wildlife viewing. Parking is a handful of small dirt lots, and there are no maintained trails through the standing water and thick brush. Freetown-Fall River State Forest is the easier walk, with 25 miles of trails, free parking, and hours from sunrise to sunset.
Profile Rock in Freetown is now within Wampanoag-managed land under the name Joshua's Mountain, and access and climbing rules there have changed, so check the current position before going rather than relying on older guides.
Freetown-Fall River State Forest is large, the trail markings are inconsistent, and people do get turned around. A paper map is worth carrying since coverage is patchy, and the woods are used for hunting in season.

Lizzie Borden House
22 miAndrew and Abby Borden were killed here on August 4, 1892, and Lizzie Borden was acquitted on June 20, 1893. Dr. William Dolan described 18 head wounds and an additional neck wound on Abby, and 10 wounds on the fleshy part of Andrew's head. These are wound descriptions, not a count of distinct blows.
Isabella Stewart Gardner Museum Theft
23 miTwo men in police uniforms spent 81 minutes inside the Isabella Stewart Gardner Museum on March 18, 1990, and left with 13 works the FBI valued at more than $500 million. None has been recovered and no one has been charged. The museum repaired the frames the thieves left behind and put them back on the walls as placeholders.
The Conjuring House
31 miThe Rhode Island farmhouse where the Perron family reported a haunting inspired The Conjuring. It later operated as a paranormal tourism site. Public tours have not been verified, and independent historical research disputes parts of the story attached to the house.
Salem Witch Trials Sites
36 miAccusations that began in Salem Village in February 1692 ended a year later with 20 people executed and at least five more dead in jail. The Witch House and the Old Burying Point carry decades of visitor reports of cold spots, footsteps, and voices. The last conviction was cleared in 2022, when Massachusetts exonerated Elizabeth Johnson Jr. after an eighth-grade civics class petitioned for her.
