The ruins of the medieval Šášov Castle stand above the river Hron. According to a legend, the lord of the Zvolen Castle had it built for his court joker who saved his life while hunting.
The task of the Šášov Castle was to guard the trade road and to collect toll. It became royal property in the 14th century and part of the dowry of the royal wives. In 1490 the family of Dóczy bought it from Queen Beatrix and reconstructed it into the Renaissance fort. The castle fell in decay after the Rebellion of Estates in 1708. Only some walls survive.
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.
