Fairy-tale worthy

  • Discovered in 1828
  • A 1 km stroll through a mysterious, fascinating landscape such as the first hall, which was inhabited by Palaeolithic hunters 8.000 years ago. Always against a fabulous background, full of colours and life, you will pass corridors, filled by the subterranean river Rubicon, until the big hall of the Cathedral (40 metres high)
  • The second part is visited by boat, gliding the Rubicon winding subterranean river of almost 700 m in length. Here one will discover new beauties, including a natural water fountain that sprays under the subterranean roof, forming a magnificent curtain.
  • An anecdote: it was used as a wine shelter for a while then later, during WW2, as a shelter
