Pszczyna Castle is a classical-style palace. Constructed as a castle in 13th century or earlier, in a Gothic architectural style, it was rebuilt in a Renaissance style in the 17th century. During the course of the 18th and 19th centuries, the exterior of the castle was partially changed into a Baroque-Classical style. The Classicist modernization transformed the complex into what is usually described a palace.
In its history the castle was a residence of Silesian and Polish Piast nobles, then the German von Promnitz noble clan (mid-16th to mid-18th centuries) and later the German von Pless family. The castle became owned by the state after the death of the last Prince of Pless, Hans Heinrich XV in 1936.
In 2009 it was voted as one of the 'Seven Architectural Wonders of the Silesian Voivodeship' by the Silesian authorities and is often described as one of the most beautiful castle residences in Poland.
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.
