The entrance of the three-floor bunker was guarded by four heavy steel doors
One of the most secret East German bunkers of all -- the Honecker Bunker -- has recently opened for a special series of tours. This bunker, just outside of Berlin, would have housed former East German leader, Erich Honecker and the highest levels of his government, if needed.
EuroVox headed deep underground, for a tour of the nuclear blast-proof Bunker 5001.
