The Phelps County Historical Society was organized in 1966. Our first displays appeared in the halls of the courthouse, then later, in the vacated Salvation Army building located just north of the current Holdrege City Hall. On April 22, 1975, ground was broken a half-mile north of the Country Club on Highway 183 for a 154′ x 120′ steel structure, now known as the Nebraska Prairie Museum (NPM).
