Graveyards are made and maintained by the living, as sacred places to the memory of the beloved dead.
And the social history of a parish is wrapped up in it's graveyards.
By studying graveyards we can tell who the big landowners were; who had a middling farm and who had none. We can identify the trades families engaged in. And one of the most commonly encountered trades is that of blacksmith. For graveyards, blacksmith's made iron crosses, grave surrounds, and put together grave railings. But mainly blacksmiths made the iron gates that close-off the sacred space.
