Domaine de Léoville was a historic Médoc estate owned by the Las Cases family until it was split up into three distinct properties. In 1855 it was classified as a Deuxième Cru, or 2nd Growth. Château Léoville Las Cases was created from 3/5 of the original estate at the heart of the domian. The Château has bee managed by the same family sine the late 19th century. Today it is considered to be the greatest estate in Saint-Julien, and one of the leading "Super-Seconds" in the Médoc.
