The caves of the Grotte di Castellana were discovered on January 23, 1938, by Franco Anelli and explored by him and Vito Matarrese. Even before the discovery, the hole (or entrance) in the earth was known, but was only used as a garbage dump. The caves can be visited as part of a guided tour. There are two different tours: one is about one kilometer long, the other is 3 kilometers long. The visit always begins in the Grave, a cave 60 meters deep, 100 meters wide, and 100 meters high. The second path leads to the White Grotto. The stalactites here are the color of alabaster. The second path is only accessible to a limited number of visitors, as the cave has no natural ventilation. Source: https://de.wikipedia.org/wiki/Grotte_di_Castellana More about the grotto from me: Unfortunately, pictures are only permitted in the first vault, the Grave. The grotto is privately owned. The temperature inside the grotto is 13 degrees Celsius in the first vault and 16 degrees Celsius afterward, with humidity between 60% and 100%. Sturdy shoes and a jacket are recommended. The limestone is quite slippery.

Ancient rupestrian village with church inside a PRIVATE PROPERTY. The dogs of the rural house (small/medium size) bark and call the attention of the owners to whom it will be possible to ask permission before continuing along the route and/or visiting the village.
