I have this theory regarding the Black Church (the one Ford goes to with the Child in the earlier episodes) is the same one Delores is seeing in her vision. Essentially in episode 4 we see a giant earth digger plowing through a lot of soil. So can it be that the old church building is buried beneath and what we have remaining of it is only the top bit. Can this be a way of Ford sabotaging Delores attempt to sentience in order to keep the park safe? Let me know what you think!
