The beekeeping museum belongs to the series of special museums. Since its opening in 1959, it has been taking care of the rich heritage of Slovenian beekeeping, recording, collecting, storing, documenting, presenting and popularizing it. It has its premises in a baroque mansion in the old part of the city. The collection presents three key themes that characterize Slovenian beekeeping: the indigenous race of bees, world-renowned beekeepers and painted beehives.

The first room presents beekeeping from its beginnings in hollow tree trunks to the middle of the 19th century and the renowned beekeeping teachers, writers and beekeepers: Anton Janša and Petar Pavle Glavar. Anton Janša (1734–1773) was appointed by decree of Empress Maria Theresa as a beekeeping teacher at the beekeeping school in Vienna. In two books, he presented his own method of beekeeping, which he successfully practiced at the Viennese school, and some important findings from the biology of bees. Priest Peter Pavel Glavar (1721–1784) was a successful agricultural and beekeeping businessman, author of proposals for improving beekeeping and introducing beekeeping schools, author of the first Slovenian beekeeping text.

The material in the second room covers the period from the middle of the 19th to the middle of the 20th century. In addition to sophisticated beekeeping tools and various types of hives, the world-famous Jan Strgar (queen breeder and trader) and Mihael Ambrožič (trader of live bees), modern beehive constructor Anton Žnideršič, important beekeeping writers and beekeeping literature are presented here.

The central part of the museum is dedicated to the painted facade boards of beehives – beehive extensions. In the middle of the 18th century, paintings appeared on the front pages of folk hives in Kranjič. Suggestions for motifs were depictions in church art, illustrated bibles, portraits, paintings on glass, graph sheets. There are over 600 different motifs known so far.

Motifs with religious content are more numerous and older. Among the most frequently depicted are Mary as the universal protector, which is also depicted on the oldest known suffix (from 1758). The group of secular motifs consists of fantasy scenes (e.g. animals in human role, making fun of craftsmen, of human mistakes), hunting scenes, historical themes (military scenes, historical figures) and scenes from everyday life.

The painting of suffixes, which flourished between 1820 and 1880, began to decline at the turn of the 20th century. Painting on the front boards of beehives is a specialty of the Slovenian Alpine area and an indispensable part of Slovenian folk art.

In the biology room, the visitor learns about the biology of the autochthonous Slovenian race of the Carniola bee or the Carniola lavender. Close-up shots of bees, presentation of the main bee pastures, sounds from the hive, live bees in the observation hive (from spring to autumn) and shots of bee pastures vividly show the life and work of bees. The main theme is rounded off by the presentation of the symbolism expressed by the character of the bee (e.g. medals, money).

Modern beekeeping is illustrated with a life-sized part of the Gorenje-type apiary and modern beekeeping tools. At the same time, the space is dedicated to video presentations about bees and beekeeping in Slovenia.

The journey through the museum ends in the room for occasional and casual exhibitions related to beekeeping (e.g. an exhibition of carved models for small bread, a presentation of a maker of copies of endings, products of children from kindergartens and primary schools…).
