In the course of the castle expansions by Count Philipp von Eulenburg (1847-1921) in the years 1891 to 1905, under the direction of the Munich architect Gabriel von Seidel, numerous mostly historicist buildings were built, which were intended to round off the castle complex into a representative overall ensemble. These included the Nordic Hall, the large gate building with tower and passageway, the connecting building to the archive building, the fountain house, the lion's gate, the hunters' houses at the entrance to the castle and the castle chapel.
The castle courtyard was only separated from the farm courtyard by the Nordic Hall with the gate tower and was given its closed, medieval appearance, which can still be seen on old photos today. Kaiser Wilhelm II, who went hunting in Liebenberg every year, was very impressed by the Nordic Hall. The actual Nordic Hall with the adjoining hunting and weapons hall was a decorative room, decorated with the prince's hunting trophies. The Nordic Hall was used for social gatherings, including the so-called Liebenberger Round Table.
In 1945, the Nordic Hall burned down with the adjoining buildings, the distillery and the administrator's house for reasons that are unclear. Today's rebuilt "Nordic Hall" respects the floor plan of the former building and essentially the former proportions, without representing a historical copy. The former facade silhouette is made clear by an iron trellis.
