"The Dickeyville Grotto and Shrines erected in the Village of Dickeyville, Wisconsin on Holy Ghost Parish grounds are the works of Father Matthias Wernerus, a Catholic Priest, Pastor of the Parish from 1918 to 1931. His handiwork in stone, built from 1925-1930, is dedicated to the unity of two great American ideals-love of God and love of Country. These religious and patriotic shrines were constructed without the use of blueprints.
It is a creation in stone, mortar and bright colored objects-collected materials from all over the world. These include colored glass, gems, antique heirlooms of pottery or porcelain, stalagmites and stalactites, sea shells, starfish, petrified sea urchins and fossils, and a variety of corals, amber glass, agate, quartz, ores, such as iron, copper and lead, fool's gold, rock crystals, onyx, amethyst and coal, petrified wood and moss."
