ETNA, Maine — Fire crews from five towns battled a fire Friday morning that destroyed a building at Camp Etna on Dover Street.

Capt. Aaron Brown of the Etna Fire Department said he received the call at 5:30 a.m.

“We got on the scene within minutes and there was heavy fire coming out the backside of the building to the point where the upstairs had already fallen through,” said Brown.

The State Fire Marshal’s Office said it was notified but will not be investigating the fire.

No one was inside the 15-by-20-foot building, said Brown. There were no injuries.

Brown said seven buildings were near the fire. He added that firefighters were lucky the wind was blowing in the direction that it was because otherwise additional buildings may have caught fire. No other buildings were damaged.

The building was destroyed, he said.

“It’s a lost cause,” said Brown. “It’s still standing — just heavy, heavy fire damage.”

The Etna, Carmel, Newport, Dixmont and Plymouth fire departments assisted at the scene while crews from Stetson and Levant were on standby.

“Good response from all the crews. Mutual aid did a good job,” said Brown.

The fire was knocked down within a half hour, he said, although there were a lot of clothes and household items that continued to smolder.

Camp Etna is a spiritual camp located on 27 acres near Etna Pond. It was founded more than 135 years ago, according to its website.
