On Fort Snelling's Upper Post, it's too late for building No. 63.
Just two years ago, the quartermaster's building was a candidate for renovation. But small holes in the roof grew bigger, and after a heavy snow about half of the roof collapsed. All that's left of that end of the once-handsome building is a tumble of bricks, splintered timbers, twisted metal and fallen red shingles.
Federal, state and county officials gathered at the Upper Post on Monday, vowing that such a historic loss would not happen again.
The 141-acre area, designated as one of the nation's top most endangered historic sites, has been a pivotal piece of land throughout Minnesota's saga.
It has served as a trading post and base from which campaigns against Indians were waged as well as a training ground for troops from the Spanish-American War to World War II.
After years of faltering efforts to save the Upper Post, officials said they are considering seeking congressional approval to clear up the tangled ownership of the site and set up a local commission to coordinate redevelopment of the 27 remaining and deteriorating buildings.
Similar commissions oversaw rehabilitation of historic military sites, including the Presidio in San Francisco and Fort Vancouver in Washington, said Peter McLaughlin, Hennepin County commissioner.
"This is a great treasure," he said. "The conditions of the buildings are unacceptable. We need to find a way to sustainably redevelop the site."
