Achilleion ... Corfu...

Achilleion is a palace built in Gastouri on the Island of Corfu by Empress (German: Kaiserin) of Austria, Elisabeth of Bavaria, also known as Sisi, after a suggestion by Austrian Consul Alexander von Warsberg. Elisabeth was a powerful woman obsessed with beauty, but was deeply saddened by the tragic loss of her only son, Crown Prince Rudolf of Austria during the Mayerling Incident in 1889. A year later she had this summer palace built in the region of Gastouri, about ten kilometres to the south of the city of Corfu in formerly, the municipality of Achilleio; now part of the Corfu municipality. Achilleion's location provides a panoramic view of Corfu city to the north, and across the whole southern part of the island.
