Set includes pageantry sleds from the Urach castle. Pageantry sleds became for the most part attic objects after the French Revolution. Ludwig II may have been the last monarch who indulged in jingle belled cross country sled rides (vanguard of torch riders, some Syberberg movie footage). Single seated snowmobiles came later (Brezhnev goes Bombardier).
Old 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.
