The exhibition opened in 1995 and is still the only children's museum in Slovenia. The museum for children draws its contents both from the past and the present, from festivities and everyday life. The museum collects, keeps, researches and exhibits the Slovenian mobile cultural heritage. It houses two collections connected to children and their lives. Children are guided through the museum by Herman the Fox, the all-present museum's mascot. Herman can be seen in the exhibition spaces, in the storehouse, the playing room, the gallery, the confectionery and in other places. With diverse forms and methods of work, the Children's Museum Herman's Den helps children discover and understand the world.
