Les Carrières de Montmartin – Carrière des Gravelets
The site is located in Montmartin-sur-Mer, where the quarries were used to extract the stones used to build the Regnéville-sur-Mer lime kilns, the Alexandre III bridge in Paris, roads and, above all, the houses in the village of Montmartin. The site can be discovered at the end of a small road, forming a cirque where the Horizon Vertical climbing club comes to practice.
