The Oper Leipzig technical cabinet houses over 300 pieces of historical lighting equipment from almost 150 years of theatre history. Initially founded in 1984 as a training cabinet for stage craftsmen and lighting technicians, the technical cabinet is now a place of collecting and preservation. Spotlights, signal boxes and colour changers found in numerous German theatres over the years are lovingly restored and cared for, their historical backgrounds researched and processed. In addition, the cabinet has extensive archive and documentation material that is used to systematically catalogue the exhibits and is being digitised step by step.
