Would my town be ghost proof?

It's probably not but I thought it would be really funny if it was

My town is built on massive salt lakes, assuming rock salt and not sea salt, and we had/have brine baths that are saltier than the dead sea, so the ground is like super duper salty.

We also have like a butt ton of churches and chapels considering it's a town, about 5 or 8 (catholic, baptist, CofE, Methodist and more), which is like half of the amount of pubs we have, which is impressive in my opinion. And apparently according my memory of what happened in that one episode in s1 with the car, ghosts can't go onto holy grounds. Which we happen to have quite a lot of.

Even more, we have a Saint and a miracle to do with salt it's genuinely like one of those towns that has that one thing that everyone talks about. We have a whole museum about our history with salt, romans paid wages with oit salt and we were called saltwich by vikings at some point we're so salty.
