Josip Nikolaj Sadnikar Collection, Kamnik
In over 60 years of collecting Josip Nikolaj Sadnikar collected over 3,000 items of historical and cultural importance, also with the help of his wife, who shared his passion for antiquities, especially of precious porcelain and crystal. He was the third honorary citizen of Kamnik (in 1937), only after a general Rudolf Maister and a poet Oton Župančič.
In 1964 the Kamnik Intermunicipal Museum purchased half of the collection. The remainder of Dr Sadnikar's collection is now preserved in the family's house in the old centre of Kamnik, in Šutna. Today the collection is managed by his son, Niko Sadnikar, also an amateur of Kamnik's heritage.
There are also two others private amateur museum collection on display in Slovenia, although are no longer in the original private ownership: the Soklič Museum in Slovenj Gradec, now under the management of the Koroška Regional Museum, and the Leopold Kozlevčar collection in Šentvid by Stična, later donated to the Stična Cistercian Abbey.
The collection and the neoclassical house in Šutna from the beginning of the 19th century are declared as a cultural monument. The rooms are decorated with antique furniture while the walls exhibit the most interesting items of sacred art and paintings by late 19th-century Slovene artists such as Maksim Gaspari and his first depiction of Zaprice Castle, Guidon Birolla, Hinko Smrekar, Ferdo Vesel and others; antique porcelain and glass, mediaeval arms, a cave bear skeleton, carpets and Chinese and Japanese works of art are also on display. The collection contributed the basic material for an exhibition of Slovene cities in 1931 in Ljubljana.
