I am looking for where this old tile belongs that I rob my ex a cathedral

Something like 30 years ago, mine stole this tile of a cathedral in Spain where they were making renovations. (According to him, the information employee or teacher became the silly when he requested information about the inquisition? How to pretend that none of that had happened there. Ask me because I separated 🤦) said that it was Arabic and ancient, I imagine very valuable.
When we separated 23 years ago I found it in my boxes. Only now it occurred to me that I can find where Reddit comes from. Does anyone know a historical building cathedral who were fixing a tile section 30 years or something around? Or do you know anyone who works in that? I want to return it. I live in Chicago.
