The charnel house and eight cemeteries abutting the cathedral's side and back walls closed due to an outbreak of bubonic plague in 1735, the bones within them were moved to the catacombs below the church. Burials directly in the catacombs occurred until 1783 when a new law forbade most burials within the city. The remains of over 11,000 persons are in the catacombs.

The basement of the cathedral also hosts the Bishops, Provosts and Ducal crypts. The most recent interment in the Bishop's crypt completed in 1952 under the south choir was that of 98-year-old Cardinal Franz König in 2004. Provosts of the cathedral are buried in another chamber. Other members of the cathedral chapter are now buried in a special section at the Zentralfriedhof.

The Ducal Crypt located under the chancel holds 78 bronze containers with the bodies, hearts, or viscera of 72 members of the Habsburg dynasty. Before his death in 1365, Duke Rudolf IV ordered the crypt built for his remains in the new cathedral he commissioned.

In 1956, the two chambers were renovated and their contents rearranged. The sarcophagi of Duke Rudolf IV and his wife were placed upon a pedestal and the 62 urns containing organs were moved from the two rows of shelves around the new chamber to cabinets in the original one.
