The Collection of Musical Instruments of Franjo Ksaver Kuhač is stored in the Ethnographic Museum in Zagreb. It contains 57 items that Franjo K.  Kuhač collected between 1857 and 1886, during field research in Croatia, but also throughout the Balkans. He sold the Collection to the Croatian Music Institute in Zagreb in 1886 for 100 forints. It was stored there for 34 years. The Croatian Music Institute handed it over to the Ethnographic Museum in Zagreb for safekeeping and permanent storage in 1920, just one year after the institution was founded. The musical instruments collected by Kuhač are extremely important, not only because they are the oldest preserved pieces, some of them more than 250 years old, but also because they demonstrate the continuity of musical traditions in a certain region.
