Ostankino Palace is a former summer residence and private opera theatre of Sheremetev family. Extant historical Ostankino includes the main wooden palace, built in 1792-1798 around a theater hall, with adjacent Egyptian and Italian pavilions, a 17th-century Trinity church, and fragments of the old Ostankino park with a replica of Milovzor folly.
Ostankino Palace is the real gem of Russian art of the 18th century, where the theatrical room with a stage, auditorium, makeup rooms, architecture, sculpture, painting, graphics and decorative art are in unison. The palace was built according to the plan and order of Count Nikolai Petrovich Sheremetev - one of the most distinguished and wealthy people of his time. Sheremetev was passionate about the theater, had a magnificent troupe of serf actors, so the heart of the summer residence was a theater with a unique theatrical machinery. The interiors of the main halls have preserved the original decor and decoration. Special elegance is attached to the halls of lighting fixtures made of crystal, bronze, gilded carved wood. Construction continued from 1792 to 1795, although the first projects date back to 1790, and the final decoration by 1799.
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.
