Nový zámok (literally 'New Castle') is a six-floor Renaissance building with four bastions. It was constructed in 1564–1571 as a watch tower during the Ottoman wars. Because of its dominant position, it was also used as the town's live clock (exact time was announced every quarter of an hour on a trumpet).
A permanent exhibition called Anti-Turkish Wars in Slovakia is installed on four floors of the castle. The highest floor offers a panoramic view of Banská Štiavnica and its environs.
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.
