The state fire marshal’s office is investigating a five-alarm fire that ripped through a historic building in Brigham City on Sunday night.

According to Brigham City spokesman Rick Bosworth, the fire at the Baron Woolen Mills at 100 S. 500 East was reported at about 9 p.m. Firefighters who were first on scene reported fire in a tin structure to the rear of the building, and the roof of the main structure fully engulfed.

“It was a shame to see it burn,” he said.

The Brigham City Fire Department, with assistance from neighboring communities, was able to put out the fire by about 10 p.m., but firefighters remained on scene until the early morning hours on Monday to work on hot spots. The cause of the fire remains under investigation.

Bosworth said quick response and a lot of manpower contributed to the relative speed in which the fire was extinguished, but the fire also moved through the abandoned building very quickly.

The investigation into the cause of the fire and the amount of damage incurred is just beginning, so Bosworth said he was unable to say what the future holds for the building.

Baron Woolen Mills was built in 1869-70 and was part of the Brigham City Co-op. In 1915, the Baron family of Brigham City took ownership of the building and operated it in multiple capacities through 1988.

The building was sold but has remained vacant since and has become a popular location for ghost hunters.

Sunday’s blaze is the fourth time the former textile business has caught fire.

The first fire destroyed the building in 1877 and another fire destroyed it again in 1907. Thomas Baron rebuilt the mill in 1923 and operated a successful business manufacturing various woolen products, including blankets, underwear, dresses, blazers, sweaters and scarves.

A third, less-substantial fire caused serious damage to the building in 1950.
