I would guess 40x60 although I did not measure it. This is a very interesting barn, at first glance I would have said it was much newer than 1851 due to the fact that it has sawn joists in the basement instead of the hand hewn sleeper logs that we usually see in older barns. However, it is a king post barn instead of the typical queen posts that we usually see which to me indicates older. Also, this is the second barn that we've seen with sawn joists from that time period. The other is near Indianapolis and was built by a wealthy/influential man who was able to order in sawn lumber instead of having it hewn onsite. I would assume the same must be true of this one.

Would love to find a new home for this barn if restoring in place is out of the question, 1851 is pretty rare for this area. Especially with the history it has. Unfortunately it has a lot of damaged timbers already, so time is of the essence if we are to save this one.
