is the firearms themselves, which are displayed in two armoury rooms at Lobkowicz Palace, while further items from the collection are held at Nelahozeves Castle. The majority of these rifles and pistols were produced locally for the family between 1650 and 1750, by the 17th-century Prague workshops of Adam Brand, Paul Ignatius Poser, the Neireiter family and Leopold Becher, as well as Roudnice craftsmen such as Johannes Lackner and Adel Friedrich during the mid-18th century. These exhibits reflect the patronage of the Lobkowicz family, who provided the gun makers with large orders for guns for many centuries. The collection features a group of identical flintlock rifles produced for the Lobkowicz Militia in the 18th century, one of the largest collections of such items. Additional weapons came from Silesia, while the most elaborate 18th-century rifles and pistols (some in the Turkish manner) with mother-of-pearl inlay were produced in Vienna. Goldsmiths and silversmiths specializing in inlay were employed to decorate guns, rifles, crossbows and powder flasks of the finest quality. The palace housed an exhibition of the work Illustrated geography and history of Bohemia by Bavarian cartographer Mauritius Vogt. The exhibition ran until 31 May 2015. Lobkowicz Collections o.p.s.
