 Construction of the Crystal Shrine Grotto began in 1938.The grotto is a 60-foot (18.3-meter) deep, hand-built cave in a hillside near the center of the cemetery, filled with five tons (4.5 metric tons) of quartz crystal, hence the name "Crystal Shrine Grotto".The shrines in the grotto illustrate the stages of "Christ's Journey on the Earth from Birth to Resurrection".
