GREAT BARRINGTON, Mass. — Firefighters battled a one-alarm fire late Thursday night that threatened to destroy a downtown landmark.

Fire Chief Charles Burger said firefighters responded just after 11 p.m. to Martin's Restaurant, 49 Railroad St., where they found fire in a first-floor kitchen of a two-story downtown block with attached exposures.

Police Officer Chad Shimmon was on the scene discharging an extinguisher through an open window, which helped slow the fire growth. The second-floor apartment was searched to verify it was unoccupied. The first engine on scene was able to quickly control the fire while additional crews checked for extension, ventilated and performed salvage operations.

Fire damage was limited to the first-floor kitchen, though there was smoke and heat damage throughout the restaurant. Second-floor tenants were able to return to their apartment after firefighters ventilated the residence.

The popular restaurant owned by Martin Lewis is open from early morning to late afternoon.

Twenty-one firefighters from Great Barrington responded to Thursday night's fire. The department was assisted on scene by the Lenox Fire Department's Rapid Intervention Team, Great Barrington Police and National Grid. Southern Berkshire Ambulance, along with the Fire Department's Support Group, were on scene providing firefighter rehab. Sheffield Fire covered Great Barrington's fire station.

"I am proud of the quick work done by our department last night," Burger said in a statement. "I would also like to thank all the agencies who assisted us. We were able to save a downtown landmark in Great Barrington."

The business is insured. The cause is under investigation, but is not considered suspicious.
