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.
The Walls of Constantinople are a series of defensive stone walls that have surrounded and protected the city of Constantinople (today Istanbul) since its founding as the new capital of the Roman Empire by Constantine the Great. With numerous additions and modifications during their history, they were the last great fortification system of antiquity, and one of the most complex and elaborate systems ever built. They were also the largest and strongest fortification in both the ancient and medieval world.
Initially built by Constantine the Great, the walls surrounded the new city on all sides, protecting it against attack from both sea and land. As the city grew, the famous double line of the Theodosian Walls was built in the 5th century. Although the other sections of the walls were less elaborate, they were, when well-manned, almost impregnable for any medieval besieger.
