Exhibited in the palace.
Colorful specimens in the natural history cabinet give an idea of the prince-bishops’ deep interested in natural history and also demonstrates the beauty and variety of their collection, which thrilled so many. The collection was assembled by Capuchin father Andreas Rettich von Marchthal and expanded and organized by naturalist Johann Caspar Abel, von Rodt's private secretary. Some of the shells even originated from James Cook's expeditions!
The prince-bishop also collected interesting fossils.
The natural history cabinet includes roughly 900 Öhningen fossils, fossilized remnants of plants and animals, which were once described as “by far the most famous attraction in Constance….” The prince-bishop could claim ownerships of the fossils because the Augustinian monastery in Öhningen, on whose property the two quarries were located, were under his control. Today, 17 Öhningen fossils from the prince-bishops’ collection are on display in the palace, on loan from the State Museum of Natural History Karlsruhe.

The significant collection of “small conchs”, houses for small mollusks, attracted particular attention. It boasted exotic, never-before-seen specimens with imaginative names: cribrarula cribraria, cypraecassis rufa, mitra papalis, mitra mitra, turbinella pyrum. Some of the richly varied shapes and colors of shells and snail houses, along with a variety of fossils, are once again on displayed in the bel étage of the New Palace, a room that once served as the royal audience chamber.
The prince-bishop’s remarkable collection included the most unusual snails.
