The natural sculpture of the Causse Noir

by | Feb 8, 2024

The natural sculpture of the Causse Noir The Causse Noir is known for its spectacular rock formations that tell us all about the region’s geological history. The landscape is littered with natural sculptures which seem to have escaped from some world of giants. Abrupt cliff-faces and natural arches, each rock formation seems to be a fragment of some monumental artwork created by mother nature. These rock formations also provide refuge for a diverse range of plant and animal species which have adapted to this unique environment. The Cité de Pierres of Montpellier-le-Vieux in the heart of the Causse Noir, is a genuine open-air museum where the rocks have become natural and living sculptures with a mysterious past silently telling us of nature’s unwavering power.

History & Geology

Long before mankind first appeared on the Earth, over 170 million years ago, the geology of Aveyron began to form under a tropical sea with an abundant marine life. 10 million years later the remains of these living organisms would leave a 300 metre thick layer of limestone on the ground. The formation of the Alps and the Pyrenees, 100 million years ago, gave rise to a series of parallel fault-lines much like those of glaciers. After 80 million years, the Causse Noir region emerged and erosion sculpted the limestone landscape into spectacular forms which came to resemble unique and monumental natural sculptures.

The Cité de Pierres was first explored in 1884 and then mapped in 1885 by the famous explorer Edouard Alfred Martel, it is located in Montpellier-le-Vieux and includes a unique concentration of narrow passages, dead ends and cirques carved into the living rock and forming into the architecture of an imaginary city littered with natural sculptures, each one more spectacular than the last.
