The mausoleum was originally the resting place of Queen Luise, the wife of Friedrich Wilhelm III. Following the death of Friedrich, Queen Luise's tomb was moved to make room for her husband's tomb.
Description
Friedrich's second wife was also placed in the mausoleum (without a tombstone). In the 1890's the tombs of Kaiser Wilhelm I and his wife Auguste von Sachsen-Weimar were also added to the crypt.
