Rohan Castle (French: Château des Rohan, German: Rohan-Schloss), also known as Château Neuf (New Castle), is an eighteenth century neoclassical palace in the city of Saverne in Alsace, France. It was one of the residences of Archbishops of Strasbourg, rulers of the Prince-Bishopric of Strasbourg, which was an ecclesiastical principality of the Holy Roman Empire from the 13th century until 1803. A series of members of the House of Rohan held the see in the 18th century.
