We've had a few of them in Wales, UK. I take photographs and manage a profile on Find A Grave. One cemetery literally a mile away - is totally out of bounds to anyone. I tried the Council, they told me to try Archives, they in turn told me to "try and find" a church spokesman. As yet - never found anyone - though I can peep through the metal solid doors (gap between the doors) that it is a very old cemetery.
Other cemeteries were moved and in one playground/park - all the headstones are lying against a wall. Apparently some stones of some graveyards were sold off as it was unconsecrated ground.
Many thanks Christine for raising awareness.
