The Monument to the Battle of the Nations (Völkerschlachtdenkmal) is dedicated to the 1813 Battle of Leipzig, also known as the Battle of the Nations. Paid for mostly by donations and the city of Leipzig, it was completed in 1913 for the 100th anniversary of the battle at a cost of six million goldmarks.
The monument commemorates Napoleon's defeat at Leipzig, a crucial step towards the end of hostilities in the War of the Sixth Coalition. The coalition armies of Russia, Prussia, Austria and Sweden were led by Tsar Alexander I of Russia and Karl Philipp, Prince of Schwarzenberg. There were German speakers fighting on both sides, as Napoleon's troops also included conscripted Germans from the left bank of the Rhine annexed by France, as well as troops from his German allies of the Confederation of the Rhine.
The structure is 91 metres tall. It contains over 500 steps to a viewing platform at the top, from which there are views across the city and environs. The structure makes extensive use of concrete, and the facings are of granite. It is widely regarded as one of the best examples of Wilhelmine architecture. The monument is said to stand on the spot of some of the bloodiest fighting, from where Napoleon ordered the retreat of his army.
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.
