As I mentioned on the Towns Along the Mississippi, we drive into lots of little towns just to see what we can see. So we stumbled upon this Grotto at the Holy Ghost church in Dickeyville, Wisconsin. It was built by Father Mathias Wernerus between 1925 and 1931. In reading a brochure I was glad to learn that he had help from parishioners but nevertheless, we were overwhelmed with the magnitude of his endeavor and the patience that it must have demanded. Any mosaicer or quilter of small pieces, should be fascinated.
