[SOLVED]
A couple that loved each other but were forbid to be. They were exhumed, and the two were reburied in a mausoleum fashion with each of their tomb stones reaching out for each other. They’re hands do not touch, As the woman was married to another man.
I can’t remember the story. Apologies if some of the details are wrong.
I think the story you have in mind is the semilegendary tale of the Lovers of Teruel. Check it out and tell me if it is that one or a different one
