Rohan Castle, also known as Château Neuf, 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. The 140 metre wide façade of red Vosges sandstone is considered to be one of the most impressive examples of its kind.
The building was erected between 1780 and 1790 by the architect Nicolas Salins de Montfort on the site of the previous building, which had been built in 1670 and burned down in 1779. This previous building had in turn replaced the small Château Vieux of 1417, which is still preserved today. That building saw two of the three marriages of Charles, Prince de Soubise; firstly in 1741 to Anne Therese of Savoy and secondly to Anne Victoire of Hesse-Rotenburg in 1745.
