Žovnek Castle lies above Lake Žovnek. The Lords of Žovnek, later Counts of Celje, were named after the castle. The castle was first mentioned in 1278 as Castrum Sevnekke, and later as Sannegg. Its history goes back to at least the 12th century. The Žovnek noble family used to live there at the end of 12th century, but their descendants moved to Celje (Cilli) in 1333 and went to aquire title and estates, becoming the Counts of Cilli.
Since 1995, the castle has been restored by a group of volunteers within the framework of the Cultural and Historical Society in cooperation with the Municipality of Braslovče, and many of its covered rooms have been used in all their glory. From the castle, which is reached by a footpath and offers a pleasant walk, there are views of Lake Žovne, the northern peaks of the Posavje hills, the wooded slopes of the Dobrovelj plateau and even Celje.
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.
