The current episode 5 "Betondeckel" is about "three holes in Salzgitter-Thiede".

There are a total of 50 Salzgitter secrets to discover, one episode every month. The premiere is always on the City of Salzgitter's YouTube channel, after which the contributions can also be seen on the city's other channels, such as Facebook.

Further contributions will follow in the coming months. A variety of stories from the Salzgitter region will be presented on film.

The whole thing is also available in book form in Salzgitter bookshops and from mail order companies.
