When I first came to live in the remote wilds of Scotland, the relatively small graveyards placed in the middle of nowhere, were a constant curiosity. Churches were not adjacent nor necessarily within view of these places. It was even more curious to me, to find that the isolated graveyards were 'invisibly' linked to a particular church.
I was used to urban living where the majority of churches of whatever Christian persuasion, were big edifices with enormous spires reaching high, were surrounded by graves of people who passed through a long time ago, and some who were more recent.
There were municipal grave yards that sprawled for miles, where the departed were interred after a religious service elsewhere that was out of sight. This is without a doubt a more generic arrangement for arranging a final farewell. Here, in my part of Scotland. The municipal grave yard encompasses views of all the churches within the town.
Mostly the separate graveyards that do belong to a particular church are the ones I have seen in this part of Scotland. That being said, I should mention I have seen variations on this theme elsewhere.
In Quebec, we found a church yard with no church anywhere in view.
Le Mairie was visible but closed. There was no church to be seen. When we investigated, we found the majority of the old grave stones bore familiar, very local, Scottish names.
