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 ancient Argos Theater was built in 320 BC. and is located in Argos, Greece against Larissa Hill. Nearby from this site is Agora, Roman Odeon, and the Baths of Argos. The theater is one of the largest architectural developments in Greece and was renovated in ca 120 AD.
The Hellenistic theater at Argos is cut into the hillside of the Larisa, with 90 steps up a steep incline, forming a narrow rectilinear cavea. Among the largest theaters in Greece, it held about 20,000 spectators and is divided by two landings into three horizontal sections. Staircases further divide the cavea into four cunei, corresponding to the tribes of Argos A high wall was erected to prevent unauthorized access into the theatron and may have helped the acoustics, but it is said the sound quality is still very good today.
Around 120 CE, both theaters were renovated in the Roman style.
