Millions of years of seismic activity, tectonic plate movement and freeze-thaw cycles created the diverse geology of present-day Provence. The region is also known as the Bouches de Rhone where the Mediterranean shoreline runs the gambit of beaches, brackish wetlands and vertigo inducing cliffs. Other natural phenomena in the area include the steep contours of the Gorges de Verdon and the volcano shaped Mont Ventoux.
The caves of Villecroze are carved into the side of a sheer limestone cliff. A grotto formed by hundreds of thousands of years of water flowing over porous rock. The continuous water created tufa rock-hard calcium carbonate deposits along the cliff face. Cycles of natural erosion and deposits formed caves of smooth stone and flowing stalactites.
