This sundial is located on the court side of the Long Hallway (Lange Gang). The Long Hallway is the connection between the Georgenbau and the former stable building. From here, the spectators watched the tournaments in the stable courtyard (Stallhof). On the street side of the Long Hallway you can find the Procession of Princes.
The small inscription tells us: Death is certain but the hour is uncertain (MORS CERTA, HORA INCERTA). A saying you can often see on old sundials.
