The Howaldtsche Metallgießerei Industrial Museum has been a site of the Kiel City and Maritime Museum since 2020. It is only open during the summer season (mid-April - mid-October). In the metal foundry, from 1884 to 1980, equipment parts for the ships of Howaldtswerke (later HDW) were cast from bronze, brass, copper and lead. The workshop of the historic building with the casting furnaces, workbenches and tools is original and can be visited during opening hours. Dates for casting demonstrations are announced on the website.
