Commissioned as a public artwork for the Memorial Park Cemetery, Crystal Shine Grotto is the largest—and perhaps only—man-made quartz cavern in the country. In 1938, Mexican artist Dionicio Rodriguez had a 60-foot-deep cave dug into the hillside in the middle of the cemetery, then set to work creating a magical attraction out of sculpted cement and almost five tons of colorful quartz crystals. He even carved niches in the walls, which were later filled with biblical statues to complete an unusual but heartfelt religious shrine that now draws thousands of visitors each year. Accompanied by a loop of harp music, the Grotto can be a peaceful place to pray, though it’s also eminently Instagrammable and has become a favorite posing spot for special-occasion photos.
