Pairie barn history

Barn logoAlso known as the Midwest Barn, feeder or Western barn, the pairie barn is the iconic image of the American barn; a peaked roof above the hay loft. They were built primarily for livestock (and the hay to feed them). This type of barn was most common in the south-central and western United States during the late eighteenth and early nineteenth century.
