Because of his title of Hofrat and his elevation into the aristocracy in 1802, Friedrich von Schiller, who died on 9 May 1805, was among those whose remains were buried in the Kassengewölbe. The mausoleum is thus often referred to as the "Schiller Vault" (Schiller-Gruft). After 1826 the Bürgermeister of Weimar, Carl Leberecht Schwabe, had had Schiller's remains retrieved from the Kassengewölbe. The exhumed bones believed to be the poet's were transferred in 1827 to an oak coffin in the newly built Fürstengruft in the Historical Burial Ground. In 2008 a DNA analysis, which attracted much attention, showed that the bones in the coffin could not have been those of Schiller, and since then the coffin, next to that of Goethe, has stood empty. It is generally presumed that Schiller's real remains were lost when the Kassengewölbe and the burial ground were levelled, although there are many other theories.
