Prof. Michal Hejcman and his colleagues describe scientific experiments in the archaeological open-air museum in Březno near Louny. A unique open-air museum was established above the Ohře River, precisely at the site of extensive archaeological research from the second half of the last century. Scientists conduct experiments to verify the various practices of the ancient inhabitants of the area. The public may also be involved in the experiments.
