The Historic Round Barn is a impressive structure. From their website:
The circumference of the barn is 282 feet, with a diameter of over 87 feet. As was characteristic of round barns, the barn was constructed around a central silo measuring 60 feet high and 12 feet wide, with storage capacity of 145 tons of silage. The silo acts as the "hub" of a wheel, with 38 "spokes" that form the interior structure and support for the second floor. All but one of the "spokes" are single lengths of wood -- each nearly 37 feet long!! The barn as it was originally constructed could house 50 head of cattle and about 16 mules or horses.
The ground floor now holds the store while an upper floor can be rented for events and parties.
The barn sits on a restored apple orchard which was originally planted in 1878 by Noah Sheely.
And of course my favorite part of visiting the Historic Round Barn is the petting zoo. I almost always make a beeline to the critters when given half a chance.
