In this excerpt from the History Channel they travel to an amazing shrine in the American heartland, West Bend, Iowa, which is built entirely out of minerals. A conglomeration of nine grottos depicting scenes in the life of Jesus, the Grotto contains a large collection of minerals and petrifications and is believed to be the largest grotto in the world. It is also "considered to be the world's most complete man-made collection of minerals, fossils, shells, and petrifications in one place." The total value of all the rocks and minerals which make up the Grotto is over $4,308,000. Over 100,000 people visit the Grotto each year. Video is good quality and has information for students studying these areas of the United States.
