There are 8 unique steel armatures that rest on cobblestone formations surrounding the bowl. Each armature points at a specific constellation, according to dates and times indicated on the panels surrounding the central stage. Sighting rings on the armatures identify specific stars within the constellations. The supporting cobblestone formations bear inscriptions of various legends about the stars their armatures focus upon. The amphitheatre marks the vernal and autumnal equinox and the summer and winter solstices. "The south armature features a shadow rod that casts solstice shadows on ground markers, the west armature is fitted with a wind sculpture, and the northeast armature features an aeolian harp."
