The round barn design was popular in Pennsylvania and West Virginia in the early 1900s. Amos Hamilton built this dairy barn in 1912. It was built by family and neighbors using lumber from his farm. The total cost was about $1,800.

It is constructed with oak and sided with yellow poplar. The barn held 25 cattle and 7 tons of hay. The barn is 62'in diameter and 75' tall.

In 1983 the West Augusta Historical Society purchased and restored the barn. It is now operated as a museum.

The barn is located near Mannington, WV on Rt. US 250. Watch for signs along Rt 250 in Mannington
