A shop building at the historic Martinsburg Roundhouse Center in Martinsville, West Virginia. The center includes 13 acres with three B&O Railroad shop buildings. The main attraction is the completely enclosed 1866 cast iron frame roundhouse. It is situated along 1,000 feet of the Tuscarora Creek. The B & O Railroad shops operated until 1988. This site was active early in the Civil War and was the site of the first National Labor Strike of 1877. Photo by Carol Highsmith, 2015.
