Along with the Krodo Altar it is one of the most important, surviving artefacts from the demolished cathedral.
The throne comprises three sides (a backrest and two armrests), which were cast from bronze, and a stone plinth with a seat.
The imperial throne stood in the Collegiate Church until its demolition (1819–1822) and was then sold.
Passing through various hands, it came into the possession of Prince Charles of Prussia in 1871 and was used for the last time in an imperial ceremony at the opening of the first Berlin Reichstag as the seat of Emperor William I. Charles left the throne in his will to the town of Goslar.
The plinth and enclosure with a replica of the bronze parts are in the remaining northern porch of St. Simon and Jude.
