Seat at the Balm Castle

Rudolf III. von Sulz lived at Balm Castle with his wife Ursula and three sons (Johann, Rudolf and Alwig) until his early death. Countess Ursula and her underage sons Ludwig and Alwig lived there until the castle was destroyed and captured by the Schaffhausen family in 1449. (Johann took over the office of court judge in Rottweil). Schaffhausen later paid ten thousand guilders as compensation under imperial pressure, but insisted that Balm Castle should never be built again. Countess Ursula therefore lived in Waldshut until her death (1460).
