Vilenica Cave or Vilenica Cave at Lokev (Slovene: Jama Vilenica pri Lokvi) is the oldest show cave in Europe. The first tourists to the cave were recorded in 1633. It is located next to the village of Lokev in the municipality of Sežana on the Karst Plateau in southwestern Slovenia. Until the mid-19th century it was known as the biggest, most beautiful, and most frequently visited cave of the Classical Karst. Later it was surpassed by Postojna Cave.
