I visited here on May 22, 1997 to plan a new house for the property.
Above: southeast corner of the barn. Below: east end.I did a quick sketch of the main floor plan. Like most old barns, it's divided into four or five sections. Here's there's five sections - from left/west to right/east = 1) calf pins; 2) cow stable with stone floor under cow; 3) barn floor (this is what we called this area in our farm - its where they bring in the hay through big doors to lift the hay into loft); 4) horse stable; 5) pig pins.
The cow stable had vertical posts/stanchions to keep the cows in place when in the stable. See photo below.
