The quarry was primarily used from the 1930s through the '70s, and supplied stone for roads and buildings across the region. Today, the 100-acre, four-million-square-foot labyrinth has found new life as an underground playground. And every winter, it transforms into one of the most enchanting holiday experiences in the country with Lights Under Louisville."

Giant illuminated characters appear around bends, and more than 40 themed scenes create a mile-long Christmas parade that winds beneath natural arches and soaring stone ceilings. Last year alone, the installation featured over seven million lights and nearly a thousand sparkling figures."
