Well, since it's over half burried in a north facing bank, I originally thought it was a small icehouse, or 'root cellar'.. But one of my neighbors told me that the last he knew it was a pig shelter !! That's a long way from an icehouse !!
So I really don't know, the original roof was resting right on the walls, so it was very short on headroom , I couldn't stand up inside, and it was a dirt floor.
I put in a lousy job of a concrete floor, and added the boilers.. it works.. If I really was ambitious i'd add some insulation, but during the daytime, I really like the natural lighting, it's nice to be able to see what i'm doing without adding lighting.
I don't know the age of the building, but my neighbor told me his grandparents knew of the outbuilding when they were young.. so around 1900 I'm guessing.
I sure wish i could find some old photos of this place,,
It's on the local historical record, that's how I know the 1849 date.. but this place has had more modiifications than a Honda Civic in 'Little Mexico'..
