The collections of the Slovak Mining Museum are of an unusual character. The majority of our collections originate from regional products, in no other museum you can find such a collection. The history of Banská Sˇtiavnica has always been connected with mining. The town was not transformed into a business-market place because it was not situated on trade routes, nor was it essential for the town because rich sources of ore were sufficient. Invention and implementation of technical innovations for increasing production of ore or its more effective processing, brought improvements in production. Various artists and architects, who created monumental pieces, sculptures of The Holy Trinity church and technical innovations of mining devices, were invited to work and left excellent examples of their work for everyday use, such as the interior of the Kammerhof building with frescos and ceramic tile stoves, goldsmith products for churches and parishes, documents of book culture from the 16th to 18th centuries. The collection includes many of these items.
