Firefighters received a call at about 3:30 p.m. that the Anson plant, a former woodworking plant, was burning down.
Anson, Norridgewock, Solon, and Skowhegan fire departments assisted Madison firefighters with the blaze. An excavator was brought in to knock down walls of the building.
Madison fire chief Roger Lightbody says he called the fire marshal’s office to investigate because the building is vacant with no power to the building.
The building has been vacant for about threeor four years.
Chief Lightbody expects his crews to be on scene into the morning.
