III had the second version of a coffin designed by Christian Daniel Rauch set into the now empty Antique Temple. The coffin's famous original lay in the mausoleum in the park of Charlottenburg Palace in Berlin, which was completed for Queen Louise, who died 19 July 1810. Until 1904 the copy remained in the Antique Temple, and arrived in Spring 1877 in the Hohenzollern Museum, situated in Monbijou Palace, which was open to the public. The Monbijou Palace was destroyed during the Second World War. Planned change of use under Wilhelm II Plans for the use of the Antique Temple as a court chapel were made during the reign of Wilhelm II, the last German Emperor. The architect Ernst von Ihne drew up several designs. The first from 1904/05 suggested a conversion in the style of the Italian High Renaissance. Eight years later, in 1913, came plans for classical interior decoration. Due to other building projects and the outbreak of the First World War, the project was never realised, however. Even a suggestion from 1918, to furbish a gravesite for the imperial leadership, did not come to fruition. However, on 19 April 1921, Empress Augusta Victoria was laid in the Antique Temple, according to her wishes, and until the 1940s the Antique Temple became the final resting place of other members of the House of Hohenzollern.

The house was from 1920 the home of the abdicated German emperor. Prince Joachim of Prussia (born 17 December 1890; died 18 July 1920) The youngest son of Wilhem II died one day after a suicide attempt with an army revolver in St. Josef Hospital, Potsdam. The prince's coffin initially lay in the sacristy of the Potsdam Church of Peace and was transferred to the Antique Temple in 1931. Prince Wilhelm of Prussia (born 4 July 1906; died 26 May 1940) Prince William was the eldest son of Crown-Prince Wilhelm, German Crown Prince and his wife, Duchess Cecilie of Mecklenburg-Schwerin, as well as grandson of Wilhelm II.
