Noteworthy is also the seat of of the Museum of Nature. This art nouveau and eclectic palace from the early 20th century was built by Max Lion, the owner of Olsztyn’s brick factory. The palace was the former estate of Bergenthal from which the name of the Nagórki district was taken. The palace went through various stages. It deteriorated especially after World War II. First, in the stylish rooms fur-bearing animals were bred, and since the 70s here public housing was located. By transferring it into a museum, it kept it alive and brought about a second youth. Apart from the palace the coach house has also survived, where the following are placed: the museum library, an educational room, warehouses and workshops. The building is surrounded by a park with interesting specimens of ancient trees.
