The Natural History Museum located within the Nikola Host Park was the first regional museum in the Rijeka area, founded in 1876 when Doctor Joseph Roman Lorenz designed its concept in accordance with Vienna’s Naturhistoriches Museum. Initially, the collection was an integral part of the City Museum, but since 1945 it has operated as an independent institution with rich holdings at its current location, within which there were a zoo and an aquarium until the 1960s.
Today, the Museum is oriented towards marine research and has a specialised library in the field of biology, geology and palaeontology. Visitors can enjoy the rich collections and permanent exhibition representing the geological past of the Adriatic, oceanographic research, minerals, marine invertebrates, sharks and rays, the “Aquarium” multimedia centre and reptiles and amphibians from the Rijeka area.
