Not simply a museum with silent exhibits, but an exhibition that lets us admire the perfect work done by our ancestors and learn about power-generating technologies, from original boilers and steam engines to the combustion engines of Otto and Diesel power machinery. The well-preserved former Karl Bienert textile factory, where a number of original structures still stand, holds artefacts and equipment from the second half of the 19^th century and the early 20^th century and maintains the original ground plan from 1852. This fulfilled the Šercl family’s plan to set up a specialised restoration workshop for historic technology and present this to the general public as separate collections of artefacts. Thanks to the enthusiasm of the owners and of their supporters, machinery is acquired and then brought back to life in the workshop. An exhibition of textile production has been created in cooperation with the Department of Textile Machines at the Technical University of Liberec, while another exhibition, consisting of aircraft engines and other equipment, was set up in cooperation with the Military History Institute in Prague. There is also a permanent exhibition of aviation archaeology that maps out the aircraft accidents to have occurred in the surrounding Jizera Mountains.
