One of the more durable contributions of the German settlers of Virginia's Shenandoah Valley are the stone houses, barns, and other buildings which they construction during Colonial times. Typically made of cut limestone blocks, these sturdy buildings sometimes were designed to serve as 'forts' during Indian attacks. Thus in many Shenandoah Valley communities there is, or at least was, an 'Old Stone Fort' which had been built by Pennsylvania Germans.
