A topic about “the oldest tombstone” was listed on the Graveyard Rabbits webpage not that long ago, but if older wiser rabbits stop to ponder it (which we often do) … the question is just a little misleading. If you travel regularly through your cemeteries, you know not all the graves are made of stone!
So, with that observation in mind, are we really interested in the oldest tombstone, or the oldest grave marker … regardless of what it was made of?
Others grave “stones” have been made from bronze, cast iron, wrought iron, steel, concrete, and wood. The only question now is: how old are they?
