DANBURY — A four-alarm fire heavily damaged a converted barn serving as living quarters attached to the Inn at Danbury Friday afternoon.

Skip Moyer, deputy chief of the Bristol Fire Department, said the fire quickly went from one to four alarms, calling firefighters from more than 11 towns, including Bristol, Grafton, Hebron, Bridgewater, New Hampton, Ashland and Meredith.

Moyer said the point of origin and the cause the fire was not evident Friday afternoon, though he said investigators would know more once the heavy fire and smoke conditions in the attic were brought under control.

Bob Graf, the inn's owner, said he had been in the kitchen of the inn's restaurant, preparing for the dinner crowd, when an employee said she smelled smoke.

"I went outside to investigate and saw a thin stream of smoke coming from the barn, like someone was smoking a cigarette," Graf said. "I went inside and saw nothing and then I went up to the next floor and saw smoke coming from the bedrooms, then the alarms went off and I left."

When he went outside, he saw flames coming out of the attic space.
