Lietava Castle was built after 1241, most likely as an administrative and military centre. In the early 14th century, it is mentioned with Máté Csák III, one of the powerful magnates in the Kingdom of Hungary. The castle changed hands until the 16th century when the Thurzó family gained it. It was reconstructed and fortified, and given its own military garrison. After the death of Imre Thurzó in 1621, it was divided between his heirs. After the ownership disputes in 1641, they lost interest in it. The castle report in 1698 said that the castle was uninhabited and there was only an archive, which was moved to the Orava Castle in the 1760s. After that, the castle was abandoned and not used any more.
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.
