People have been buried in the cemetery for over 1,400 years, resulting in literally millions of bodies there.
During the Iraq war in 2003, fighters in the Iraqi militia frequently used the cemetery to hide in, ambushing enemies. They knew the winding lanes and mausoleums better than anyone else. Since the wars and violence, the graveyard has expanded massively.
