[edit]DescriptionTycho Brahe's mural quadrant in Uranienborg.png | Tycho Brahe's mural quadrant in Uranienborg (Uraniborg). The quadrant (radius c. 194cm) was made from brass and affixed to a north-south oriented wall.

The area above the quadrant is filled with a mural painting. See Brahe's original description of the instrument. | ||||||
