Schloss Esterházy 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 architectural history of the building involves a transition from an actual medieval castle, built for defense, to a palace meant for comfort and ostentatious display. The moats were removed in the early 19th century, and the architectural style was modified at various points to fit the taste of the times.
1364 The palace comes into the possession of the powerful Kanizsai family and consequently experiences a substantial development.
1371 King Louis acquires and develops the castle into a "medieval city castle" included in the northwest perimeter of the city of Eisenstadt.
1622 Ownership falls under the possession of the Esterházy family.
After the death of Count Ladislaus Esterházy in the battle of Vezekény in 1652, his younger brother Paul inherited the palace. The additions he made took nearly ten years to complete, and gave it the facade we see today. The rich stucco decoration was made by the Italian master Andrea Bertinalli.
There were few changes made during the high and late baroque periods. In the 18th century, the interior design and staircases were about all that changed. Most areas were equipped with furnaces and stucco ceilings. The only large construction work in the palace was the renewal of the two main staircases, which are presently the same.
