Mirozhsky Monastery is a 12th century Russian Orthodox monastery complex famous for its frescoes. It is located in The Christ's Transfiguration Cathedral. The name of the monastery is derived from the name of the Mirozha River, since the monastery is located at the place where the Mirozha joins the Velikaya River, on the left bank of the Velikaya. The catholicon of the monastery is one of the two pre-Mongol buildings which survived in Pskov, and contains the unique frescoes of the 12th century.
The exact date of the founding of the monastery is not known. Traditionally, it is considered to be the mid-12th century and is associated with the name of Nifont, Bishop of Novgorod. The monastery, located 20 minutes walk from the Pskov Krom, was one of the cultural centers of the city, comprising a library, scriptorium and icon workshop.
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.
