[1] From 1913 to 1921/1924, the building was converted into a closed four-wing complex in the Neo-Renaissance style according to the plans of Gustav von Flesch-Brunningen.
The north and south wings were extended to the east, each with a round tower at the end.
The new, spacious east wing was given a show facade and a generous interior design.
