In the early 1950s, Josip Broz Tito, the late leader of the former Yugoslavia, ordered the building of a secret bunker that would safeguard the country's ruling class in case of a nuclear attack. Located 900 feet (270 m) underground, near the Bosnian town of Konjic, the 26-year project was only completed in 1979, the year before Tito died, and it was built at a cost equivalent to just under £3 billion ($4.6 billion). According to AP, if restocked with supplies it would still serve its purpose - allowing 350 people to live and work for six months without ever coming outside. Reuters photographer Dado Ruvic visited the site and documented the outdated rooms and furniture in what it feels like a tunnel to the past. Picture: REUTERS/Dado Ruvic
