This museum houses the collection of Mr. Paul Broste, a local farmer, artist and collector. He began his rock collection at an early age and did much of it during the 1920s and 30s when few people were interested in purchasing rocks. He acquired only the finest specimens from all over the world and then cut, ground and polished them into spheres and slabs of unimaginable beauty.
This world famous museum is nestled on the Great Plains of North Dakota, built of natural granite quarried from the area. Paul called it his "Acropolis on a hill". The museum houses the most significant rock and mineral collection in the state of North Dakota and many of the unique specimens are so rare that they may be only found at museums like the Smithsonian Museum of Natural History in Washington D.C. or the American Museum of Art. There are some items like the fluoride crystals in the collection that can not be found anywhere else in the world and are deemed priceless.
