Spiral of Gratitude is a permanent memorial installation located in the main lobby of the new 243,000 sf San Francisco Public Safety Building. A memorial to honor police officers who have fallen in the line of duty, Spiral of Gratitude encompasses a large glass cylinder, 17 feet tall and 10 feet in diameter, forming an oculus/skylight that frames the sky above. It is inscribed with written expressions of gratitude and loss, gathered from surviving family members and crafted into a seamless, evocative poem. The Memorial is also framed by bas relief text inscribed in the entrance lobby’s rear wall.
