Sigmaringen

Sigmaringen is a town on the upper Danube in Baden-Württemberg, Germany, dominated by a castle on a rock above the river. Granted to the counts of Hohenzollern by the Habsburgs in the 1530s, it became the seat of the Catholic Hohenzollern-Sigmaringen line, whose members later became kings of Romania. In 1944–1945 its castle housed the exiled leaders of Vichy France.
