The Armijska Ratna Komanda ARK D-0, nicknamed Tito's bunker, is a Cold War-era nuclear bunker and military command centre located near the town of Konjic in Bosnia and Herzegovina. Built to protect Yugoslav President Josip Broz Tito and up to 350 members of his inner circle in the event of an atomic conflict, the structure is made up of residential areas, conference rooms, offices, strategic planning rooms, and other areas. The bunker remained a state secret until after the breakup of Yugoslavia in the 1990s.
Built between 1953 and 1979 inside Zlatar Hill at the southern foothills of Bjelašnica Mountain, the ARK is the largest nuclear shelter, and one of the largest underground facilities, ever built in the former Yugoslavia. For over a decade after its completion, it was the most secret military installation in the country. All construction workers were carefully vetted, signing a confidentiality contract, and all staff members held the highest security clearance.
Tito's bunker now serves as a meeting point for artists from across the region, Europe, and the world. The goal of the Project Biennial of Contemporary Art is to transform a site still officially under military control into a prestigious regional cultural institution at the forefront of emerging artistic trends. The project seeks to preserve cultural heritage and a historic structure as well as to create artistic value and reestablish broken connections between artists and creative people in the region.
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.
