With the aim of providing services for its founding partners, in April 2014 the cultural foundation Kulturstiftung Sachsen-Anhalt founded its subsidiary SubsiDiariuS GmbH. The main shareholder, Kulturstiftung Sachsen-Anhalt, was joined from the start by the memorials foundation Stiftung Gedenkstätten Sachsen-Anhalt, with Dussmann Beteiligungs- und Management GmbH becoming a fellow partner in October 2014.

Since it went into operation, SubsiDiariuS GmbH has provided the founding partners with personnel-based services in the fields of security, visitor services, building cleaning, caretaking and hard facilities management. In May 2015, SubsiDiariuS GmbH also took on the “Zum Weissen Mönch” catering and restaurant business at Michaelstein Abbey. Since 2017 it has run the hotel of the same name there.

With roughly 120 employees, SubsiDiariuS GmbH provides services in the partners’ museums and operating sites.
