Grandes Canalettes cave is located at 300 metres from the medieval town of Villefranche-de-Conflent on the road to Corneilla-de-Conflent and Vernet-les-Bains, in the département of Pyrénées-Orientales, France. The cave was discovered by chance in 1951 by Mr Motte. A few years later, in 1957, the Fuilla network of underground galleries was presented to Henri Salvayre, a hydro geologist and expert in underground galleries. In 1978, he met Edmond Delonca, a driller by trade. Together they embarked on the monumental job of exploring the galleries. It was the start of a long and deep friendship between the two men. Exploration of the galleries commenced in 1981 with the help of former miner Joseph Pujol and GEK caving member Henri Lozano. Salle Blanche (the White Gallery) was discovered in 1982. Stringent planning and development studies ensued with the view of opening the unique Grandes Canalettes cave to the public.
