A bunker that was built to protect Yugoslavia's communist leadership from nuclear attacks has become an art gallery. The once-secret shelter in Bosnia is 280-meters deep and U-shaped. It was dig into a mountain, taking 26 years to create and had a price tag of billions of dollars.
It will be open as an art gallery for three months, housing works by artists from 19 different countries to be displayed in the facility's 100 rooms. Tickets will be 5 euro ($6.50), which comes with transportation and a guide. Sounds nice, but visitors also have to get a permit from the army to enter via a local tourist bureau.
