The Dickeyville Grotto & Shrines is a folk art environment constructed between 1925 and 1930 by Father Matthias Wernerus. The structures are composed of thousands of pieces of seashells, colored glass, stones, fossils, and stalactites embedded in mortar. It features several distinct shrines including the Sacred Heart Grotto, the Blessed Virgin Grotto, and the Christ the King Shrine. The complex is located on the grounds of Holy Ghost Parish in southwestern Wisconsin. It is recognized as a significant example of religious folk art in the United States.
The main path facing the Sacred Heart Grotto provides the most balanced perspective of the primary structure.
Walk the perimeter carefully to observe the intricate detail of the small inlaid stones.
Visit the small on-site museum area to understand the history of Father Wernerus.
The grounds are relatively small, so combine this with other nearby driftless area attractions.
Do not attempt to climb or lean on the structures, as the historical materials are delicate and prone to crumbling.
The grounds are typically open to the public daily, but the site may be closed during severe winter weather or parish events.
Maintain a respectful, quiet demeanor as this is an active religious site; do not touch or pick at the fragile mortar surfaces.
