Griffith Observatory Solar Calendar

The Gottlieb Transit Corridor is an accurate, outdoor, public astronomical instrument. The transit arc is mounted on the axis of the local meridian, approximately 118 degrees west longitude. Its form echoes similar instruments from ancient temples and medieval churches but updates the concept for the 21st century. Each day at local noon as the sun passes the installation, a spot of light moves across the meridian on the 7-inch wide arc and enables visitors to see how the sun’s progress is linked to the calendar.

TriPyramid worked with the designers and the Observatory staff to detail the large, bronze arc. TriPyramid then constructed the arc, manufactured and finished to the same standards of accuracy as a fine navigational instrument.
