Frankfurt Cathedral
Emperor Sigismund transferred the Imperial Regalia "to everlasting preservation" to the Free Imperial City of Nuremberg with a dated document on 29 September 1423. They arrived there on 22 March the following year from Plintenburg, and were kept in the chapel of the Heilig-Geist-Spital. Once a year they were shown to believers in a so-called "Heiltumsweisung" (worship show), on the fourteenth day after Good Friday. For coronations they were brought to Frankfurt Cathedral.
