312.HohenneuffenOld Württemberg had seven super fortresses. Four of these were mountain strongholds (Hohentwiel, Hohenurach, Hohenneuffen, Hohenasperg) and three strongly fortified cities with castle grade walls (Tübingen, Schorndorf and Kirchheim/Teck). An occasional overlap with Celtic defense structures can be observed. And some geographic features will always lend themselves to certain enhancements.
