Heather Mammen lost her daughter Elaina Mammen to gun violence in December 2022. She created the GLOW Project in Elaina's honor to spread awareness against gun violence, and the new peace garden is the latest addition to that effort. For Mammen, a peace rock in the garden represents the joy Elaina brought to the world. Mammen said the garden continues to give her purpose and keeps the memory of both Elaina and Berkeley alive. The Peace Garden, located at Cross Keys Park, is open to anyone who wishes to visit.
