A portrait within the Last Judgement
Above the Golden Gate, the mosaic of the Last Judgement dates from 1370–72. Within its religious imagery appear Charles IV and his fourth wife, Elizabeth of Pomerania. The composition connects a universal Christian story with the particular royal patrons of the Cathedral.
Three medieval windows
The Cathedral’s own art guide identifies three surviving medieval window traceries at the Old Treasury above the Old Sacristy. They can be studied from Vikářská Street, even though the rooms behind them are not part of the normal visitor route. Tracery is the patterned stone framework within a window, not the glass itself.
The treasury is not the Crown Jewels
The Cathedral treasury grew from objects used in worship and the veneration of saints. It is distinct from the Bohemian coronation regalia. Keeping those two collections separate helps make sense of references to reliquaries, royal insignia and the Crown Chamber.
Legend and evidence
A familiar legend warns of death for anyone who wears the St. Wenceslas Crown without the right to do so. It is a legend, not an established historical cause of anyone’s fate. The documented objects and their settings are compelling enough without turning folklore into fact.
