The Royal Palace of Milan (Palazzo Reale di Milano) was the seat of government of the city for centuries. Today it serves as a cultural centre and home to expositions and exhibitions.
Originally designed with a structure of two courtyards, the palace was then partially demolished to make room for the Duomo. The palace is located to the right of the facade of the cathedral opposite the Galleria Vittorio Emanuele II. The facade of the building follows the style of the ancient courtyard, forming a recess in respect to Piazza del Duomo, known as the Piazzetta Reale.
The magnificent Hall of Caryatids can be found on the main floor of the building. It occupies the site of the old theatre, which burned down in 1776 and is the only room that survived the heavy bombings of 1943. The damage caused by the incendiary and violent air movement was followed by a state of abandonment for over two years, which contributed to further serious damage to the building. Many of the neoclassical interiors of the Palace were lost.
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.
