The Musée Ariana is devoted to ceramic and glass artwork, and contains around 20,000 objects from the last 1,200 years, representing the historic, geographic, artistic and technological breadth of glass and ceramic manufacture during this time.
Built between 1877 and 1884, the museum is shaped by Neo-Classical and Neo-Baroque elements and is situated near the Palace of Nations. It was built to house the private collection of the Swiss art collector and patron Gustave Revilliod, who named it after his mother, Ariane de la Rive, and later bequeathed it to the city of Geneva.
References: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.
