The dominating feature of the Benešov nad Ploučnicí town is actually two castles from the 13th century, the Lower and Upper castles. There is a permanent exhibition of Chinese art and day and night tours are available as well as social meetings.
The history of the castle started in the 13th century when a settlement of tradesmen and shopkeepers began under the castle Ostrý. The people were satisfied there, the settlement grew and one day in 1392 Jan from Michalovice named the settlement a town. The son of the owner, Hynek Berka from Dubá, was a hussite antagonist and in 1422 he called together a congress of the antihussite catholic nobility from Northern Bohemia. The Hussites didn´t hesitate to besiege Benešov many times over the next few years.
Since, the town was protected only by a simple wall, a moat and a mound, it was rapidly plundered and burnt out. Then in 1515 the Salhausen family from Míšeň bought the castle. That was the beginning of the rise of the town. The castle was rebuilt and sold many times. In 1945 it became a possession of the state and then in 1956 it was declared a castle of the 1st category. Unfortunately, the castle was destroyed by fire in 1969. It took a couple of years before it was reopened to the public.
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.
