Aven Armand

Aven Armand is a limestone cave located in the Cévennes National Park of France, in the Lozère département, between Meyrueis and Sainte-Enimie known for the tallest known stalagmite of 30 meters.

History
It was first scientifically explored by the French explorers Louis Armand and Édouard-Alfred Martel in 1897. The cave begins as a narrow pit, descending 75 m before opening up into an enormous vaulted chamber known as the Grand Salle, or "Great Hall".

The Grand Salle is close to 100 m long and 55 m wide. The floor is covered with a proliferation of fragile limestone speleothems in a variety of shapes and sizes, created by the slow dripping of water through the stone over thousands of years. Some have reached heights of close to 30 m.

It has been open to the public since 1927, after a man-made tunnel and walkway paths were created to permit easier viewing of the Grand Salle.

In popular culture
In June 2017, French singer Nolwenn Leroy used the Aven Armand cave as a setting for the music video of her single "Gemme".
