バート・エーンハウゼン
The town was returned to local control in 1954 and spa activities resumed. In 1973, the seven surrounding municipalities Wulferdingsen, Volmerdingsen, Werste, Eidinghaisen, Dehme, Rehme and Lohe of the former "Amt Rehme" were merged with Bad Oeynhausen into one commune. The "State-owned Spa Bad Oeynhausen" (), property of the state of North Rhine-Westphalia, was municipalised in 2004.
