Luray caverns

Luray Caverns, originally called Luray Cave, is a commercial cave just west of Luray, Virginia, United States, which has drawn many visitors since its discovery in 1878. The underground cavern system is generously adorned with speleothems such as columns, mud flows, stalactites, stalagmites, flowstone, and mirrored pools. The caverns are perhaps best known for the Great Stalacpipe Organ, a lithophone made from solenoid-fired strikers that tap stalactites of various sizes to produce tones similar to those of xylophones, tuning forks, or bells.
