Schloss Umkirch, Château in Umkirch, Germany.

Schloss Umkirch is a broad, pink-walled château with a central portico and two side wings. White pilasters divide the facade, whose rectangular windows have pale shutters on both floors. The portico carries a balustraded balcony on four round columns with vines climbing between them; above rise a red-tiled gable roof with a round window and a square white belvedere, and a tall chimney stands at the right end of the roofline.

A water castle of the Lords Geben stood here in the 14th century. After the old castle was demolished in 1743, the central block was rebuilt, and the two side wings followed in 1788–1789. In 1816/17 Flora von Kageneck had the building remodelled in Italian country-house style and added the belvedere; the Kageneck-Wrbna coat of arms remains in the gable.

The castle is also called Hohenzollernschloss or Royal Romanian Castle, after Karl, King of Romania, who inherited it on 19 June 1900. In the gable the coat of arms of Kageneck-Wrbna is still visible, recalling Flora von Kageneck, who married Count Eugen von Wrbna in 1798 and had the building remodelled in Italian country-house style in 1816/17.

This property is privately owned and closed to the public, as it remains a residence of the Hohenzollern family. Visitors can view the exterior from nearby public paths that pass through the area.

The castle passed to Karl, King of Romania, on 19 June 1900, and in 1943 two princes were born here: Ferfried von Hohenzollern and Leopold of Bavaria. From 1946 to 1952 General Pierre Pène lived in the building as governor of Baden for the French occupation forces.
