Achilleion is a palace built in Gastouri on the Island of Corfu for the Empress Elisabeth of Austria, also known as Sisi. 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.
Achilleion is located about ten kilometres south of the city of Corfu and provides a panoramic view of the city to the north, and across the whole southern part of the island to the Ionian Sea.
The architectural style was designed to suggest an ancient palace of mythical Phaeacia. The motif centers on the hero Achilles of Greek mythology, from which the name is derived. Corfu was Elisabeth's favourite vacation destination and she wanted a palace to gratify her admiration for Greece, its language and its culture.
The property currently operates as a museum under the management of Hellenic Tourism Development Company, within the Greek National Tourism Organization.
Sigmaringen Castle was first mentioned in the year 1077 in the chronicles of Petershausen monastery. The oldest parts of the castle are concealed beneath the alterations made during the 17th and the 19th centuries. The secret of the earliest settlement built on this defendable rock will never be fully revealed: large-scale excavation work would be necessary, which the extensive land development renders impossible. Judging from the many Roman remains unearthed in the area around Sigmaringen, the 12th century keep known as the 'Roman Tower' could be traced back to a Roman predecessor.
The castle remains that have been preserved (gate, great hall and keep) date back to the Staufer period around 1200. The castle remains were integrated into subsequent buildings. The foundations of the castle buildings are to a large extent identical to the surrounding castle wall.
These remains give us a good idea of how the castle might have looked during the 12th century.
