The Doksany town is well-known mainly for its monastery established probably already in 1144 by Vladislav II. The heyday of the monastery was in the 13th and 14th centuries. It was completely desolated during the Thirty Years’ War. After that it was rebuilt into the Baroque appearance in 17th century. During the 19th century the monastery became a chateau.
Doksany Monastery has been used to film BBC's The Musketeers, an HBO's Knightfall series.
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.
