At one time the building had electricity and the windows would be lit up. It could use a bit of restoration, but personally I would leave it as-is.
There are pews in the main hall and a bell in the steeple. The top domes lift off, apparently for ease in moving as there is nothing visible when removed. (The gold crosses are not a part of the structure.)
If I had a place to properly showcase this, I would certainly have given it serious thought and I'm not even Catholic!
