Schloss Esterházy (Hungarian: Esterházy-kastély) is a palace in Eisenstadt, Austria, the capital of the Burgenland state. It was constructed in the late 13th century, and came under ownership of the Hungarian Esterházy family in 1622. Under Paul I, 1st Prince Esterházy of Galántha the estate was converted into a baroque castle which remained the principal residence and center of administration of the family for over 300 years. The famous composer Joseph Haydn worked here for most of his life.
