DH isnt sure what the Swiss do with the actual bodies, but he thinks their bodies deteriorate faster due to no vaults and other sutff. He isnt sure.
His mom was cremated, so when her ten years was up, her headstone was removed, she had to make room for the newly cremated person. DH again isnt sure what happened to her ashes, but 3 of her kids were just there to visit her grave (now not hers) in 2017. They stood around and talked about the former gravesite. Things are really crowded in this little kirkuard in this Swiss village, I mean the headstones are cheek by jowel. DH said the area for cremationis empied faster than the area for bodies because there are many more cremations.
