I love to visit Zentralfriedhof once in a while. My camera will be in my hand – ready to take pictures everywhere.
Some deceased are buried in deep and well secured graves. Heavy stones on the heads and gigantic slabs of granite on the bellies make sure the dead stay in their graves for eternity. Grave robbery will be almost impossible. I am sure heavy machines and a crane are needed to reopen the graves for the next burial. So the old rings and handles of some graves are more or less nice decorations but maybe they were functional at the time the grave was erected.
