The Cirque de Mourèze is a natural site located in the department of Hérault, in the south of France. It is a dolomitic circus formed about 160 million years ago, during the Jurassic period, by the erosion of limestone rock.
The Cirque de Mourèze is famous for its bizarre and dramatic rock formations , which have been sculpted by erosion over time. The boulders are mostly composed of dolomite , a sedimentary rock that is more resistant to erosion than limestone, which explains the formation of these unusual shapes.
