And, though this isn't an actual church, it is used as a church often:

Right across the street from the Temple I listed just above.

Oh, and another outside pic:

There has been discussion about the temple built in Independence, MO. It is indeed Community of Christ (certainly NOT Mormon). But, it is NOT a corkscrew, as previously mentioned. Perhaps whoever said that (and anyone else interested) should tour it (all are welcome--free tours and organ recitals, as well as daily prayers for peace and lots of church services are held there).

It is a nautilus shell.
Here are a couple of pics:
