The Hollow Earth is an obsolete concept proposing that the planet Earth is entirely hollow or contains a substantial interior space. Notably suggested by Edmond Halley in the late 17th century, the notion was disproven, first tentatively by Pierre Bouguer in 1740, then definitively by Charles Hutton in his Schiehallion experiment around 1774.
In 1963, while constructing an overpass in between Round Rock and Georgetown, Inner Space Cavern was discovered after a space was found more than once at 33 feet (10 m) below grade. A three-foot (0.91 m) hole was drilled into the space and an engineer was lowered into the hole for exploration.
The cavern began as a limestone quarry, which was mined from the early 1930s to the early 1970s. Much of the extracted rock was used to build roads throughout the Louisville area.
