Tomahawk Spring near Martinsburg in the Tomahawk area of West Virginia preserves a modest mid-19th-century spring house, built around 1860 on the stone foundation of an earlier structure. The surviving building is a one-story wood-frame structure set on a three-foot-high stone base and divided into two sections. One section stands directly over the spring and is enclosed with latticework, while the other contains a pool. Its importance rests in the rare survival of a vernacular spring house that reflects the practical use and protection of a dependable water source, preserving a tangible piece of everyday rural infrastructure.
