The Judgement Tower is a fortified medieval tower in Maribor. An original tower built on the site in the early 14th century secured the southwestern corner of the city walls. It was completely rebuilt in 1540, with the addition of a conical roof which burned down in the 17th century.
The tower has seen several additions; the renaissance structure extends to the tops of the second-floor windows, and is followed an early 17th century extension. Four more floors were added in the 19th century.
The tower partially burned down again in 1937 and was restored in the 1950s. It is one of several surviving elements of the former city walls; others include the Water Tower and the Jewish Tower, while the Benetke Tower was demolished in the late 1960s to make way for a hydroelectric reservoir.
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.
