I am not a geologist. I am a person who thinks “fancy” gravel is the stuff with the different colors. So walking into the Grotto is like being a toddler in a candy store, except the candy is millions of years old and you can’t eat it. You’ll see agates, quartz, and petrified wood jammed into every inch of concrete.
It’s honestly a little overwhelming. You’ll find yourself squinting at a cluster of sparkly rocks thinking, “Did that come from Brazil? Or did Father Dobberstein just grab it from a creek in Minnesota?” The answer is both. Literally both, from all over the world, and he carted them here by hand.
There’s a section dedicated to the Stations of the Cross. And let me tell you, these aren’t your church-basement, felt-board versions. These are three-dimensional dioramas made of concrete and gemstones that look like they’re from a biblical theme park designed by a gem-obsessed wizard.
When “Souvenir” Becomes a Life’s Work
The story behind this place is the real kicker. Imagine telling your spouse, “Honey, I’m going to the store for milk.” And then you come back with a pickup truck full of fossilized coral. That’s basically what Father Paul Dobberstein did, except for forty years. He built the whole thing as a promise to God after surviving pneumonia.

I like to think his prayers went something like: “Dear Lord, thank you for letting me survive. In return, I will build a monument that will confuse and delight tourists for generations. Also, please help me find a good source of pink agates.” And God apparently said, “Go for it, buddy.”
The man didn’t use power tools. He mixed concrete by hand. He hand-chiseled those rocks. Meanwhile, I get frustrated when the WiFi buffers for ten seconds. It puts your own “hard work” into perspective. Your “big project” for the weekend (cleaning the garage) suddenly feels a little less monumental.
