The armillary sphere consists of two meridians, the tropics of Cancer and Capricorn, the northern and southern polar circle, the ecliptic and the equatorial plane, in which the figures are cut out. In the plane of the ecliptic, 7 faceted balls made of granite are installed.
The shadow casted by the polar gnomon counts the hours in term of true solar time.
