One of the largest caves in the eastern United States, Luray Caverns in Virginia features vast underground rooms connected by natural corridors and paved walkways adorned with vibrant rock formations. Its greatest boast, though, is the Great Stalacpipe Organ, a unique instrument that creates symphonic music from stalactites. Invented in 1954 by Leland Sprinkle, a mathematician and electronics engineer, it’s recognized by Guinness World Records as the world’s largest natural underground musical instrument. It spans over 3 acres of the caverns and is a lithophone, meaning it produces sound by striking objects (in this case, stalactites) with rubber-tipped mallets.
