The Amusement Palace is located at the Kremlin’s western wall. It is situated between the Commandant and Trinity Towers. It was built in 1652 for Ilya Miloslavsky, who was the father-in-law of czar Alexei Mikhailovich. After the death of Miloslavsky, the palace went to the state. It was then used as a theatre. In the theatre performances were staged to amuse the family of the czar and his court. Hence, it got the name the Amusement Palace.
During the administration of czar Peter the Great, the Police Department was placed in the Palace. In the 19th century the Commandant of Moscow took up his residence there. The palace was restored in 2002-2004, including the original décor of its façade and the Church of our Lady’s Glorification.
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.
