Monument to the Revolution is a World War II memorial sculpture by Dušan Džamonja, located at one of the highest peaks of Kozara mountain, Bosnia and Herzegovina. It is dedicated to the fierce battle and 2,500 Yugoslav partisan fighters and 68,500 predominantly Serb civilians killed or deported to Ustaše concentration camps during the German-Ustaše-Hungarian Kozara Offensive from June to July 1942.
The initiative for the monument's construction began in 1969 and Dušan Džamonja won the first prize for his project. Construction of the monument was completed in 1972.
Džamonja himself described the monument as an interplay of light and darkness; this cylindrical-shaped monument is composed of twenty vertical segments, each being characterized by deep-set concrete pillars (positives) and hollows (negatives). While negatives symbolize death, positives represent victory and life. Horizontally-positioned concrete blocks symbolize enemy forces who are trying to destroy life and victory but are unsuccessful.
Other parts of the memorial complex include a museum and the memorial wall with the names of 9,921 Yugoslav partisans killed in battles on Kozara during World War II in Yugoslavia.
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.
