Editing Frederick William I of Prussia (section)

==Burial and reburials==
Frederick William died in 1740 at age 51 and was interred at the [[Garrison Church (Potsdam)|Garrison Church]] in [[Potsdam]]. During World War II, in order to protect it from advancing allied forces, [[Adolf_Hitler|Hitler]] ordered the king's coffin, as well as those of [[Frederick the Great]] and [[Paul von Hindenburg]], into hiding, first to Berlin and later to a salt mine outside of [[Bernterode (bei Worbis)|Bernterode]]. The coffins were later discovered by occupying American forces, who re-interred the bodies in [[St. Elizabeth's Church, Marburg]] in 1946. In 1953 the coffin was moved to [[Hohenzollern Castle]], where it remained until 1991, when it was finally laid to rest on the steps of the altar in the Kaiser Friedrich Mausoleum in the [[Church of Peace (Sanssouci)|Church of Peace]] on the palace grounds of [[Sanssouci]]. The original black marble sarcophagus collapsed at Burg Hohenzollern—the current one is a copper copy.<ref>MacDonogh, Giles (2007). ''After the Reich: The Brutal History of the Allied Occupation''.
