Grotta Gigante ("Giant Cave", Slovene: Briška jama or Jama pri Briščikih), also known as Riesengrotte or as Grotta di Brisciachi, is a giant cave on the Italian side of the Trieste Karst (Carso), close to the village of Borgo Grotta Gigante or Briščiki in the municipality of Sgonico. Its central cavern is 107 m (351 ft) high, 65 m (213 ft) wide and 130 m (430 ft) long, putting it in the 1995 Guinness Book of Records as the world's largest show cave. This record was broken in 2010 when La Verna cave in the south west of France was opened to tourists, measuring 255 by 225 by 195 metres (837 by 738 by 640 ft).
