This stone grotto is located south of Rosati on the Jim DiPardo property which was formerly the Hrunek farm, and before that, the Shields farm and the De Luca farm. It was built in the very early 1900s by Paul "Paolino" Lorenzini. He became ill and was taken to St. Louis by his son, and did not return. The grotto contained a statue at one time, and De Luca family members occasionally saw Paolino praying at it.

This may also be the place where Knobview Italians met on Sunday mornings before the first church was built. One of the original settlers was quoted as saying, "We would go to the little grotto down in the woods and pray the Rosary".
