Achilleion (Greek: Αχίλλειο or Αχίλλειον) is a palace built in Gastouri (Γαστούρι) on the Island of Corfu for the Empress (German: Kaiserin) Elisabeth of Austria, also known as Sisi, after a suggestion by the Austrian consul . Elisabeth was deeply saddened by the tragic loss of her only son, Crown Prince Rudolf of Austria following the Mayerling incident in 1889, and a year later she had this summer palace built as a refuge. The property currently operates as a museum under the management of Hellenic Tourism Development Company, within the Greek National Tourism Organization.
