Still in use ~ critical phrase. There's another structure in East Central Ohio that is probably several decades older ~ looks like a sacrasty ~ first part of a church you might build out in the wilderness before you had any parishners. You can go on the net and in moments match up the style with that of standard Spanish frontier stuctures ~ all the way back!

They owned the Ohio Valley for a good long while ~ a couple of centuries before the French tried to move in! They did things ~ long forgotten things. (SEE: Old Stone Fort ~ http://www.midwesternepigraphic.org/croghan.html )

This past spring, I was in Santa Fe on business and we were walking around looking for someplace to eat one evening. We walked right by this church. I saw it on the way by, but didn't take notice. I took the time to stop on the way back and read that very sign. Unfortunately it was closed for the day.
