Pravda Castle was a castle, the remains of which can be found on the hill above the village of Pnětluky. The name literally means the truth.
The first document to mention Pravda was written in 1380. Today's castle was probably built during second half of 15th century on top of a prehistoric fortification. At the time of construction it was a very modern and strong fortress. During the 16th century the importance of the castle diminished, resulting in its abandonment.
In modern times it has become a target for tourists and a place of meetings and festivals, during the 20th century, the castle's structure deteriorated significantly and attempts are being made to stabilize it.
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.
