This room was added in 1827 and included a sliding shutter arrangement in the roof to allow observations to be made with the Mural Circle. The windows on the north and south sides gave the astronomer views of the North and South Meridian Markers to enable him to align his instrument.

Starting from the Mural Circle, the large circular brass instrument, and moving clockwise (left to right) you can see the following (click on a thumbnail for more information);
