The Saint-Nabor promontory, located in Alsace at the foot of Mont Sainte-Odile, offers a natural site rich in history and geology. It is known for its old porphyry quarries, a volcanic rock formed in the Carboniferous period, exploited long before their closure in 2002. The promontory rises to an altitude of approximately 340 meters in a semi-continental microclimate favoring vineyards and forests. It constitutes a belvedere offering a remarkable panorama of the Alsace plain, as far as Strasbourg and the Black Forest on a clear day. The site is accessible by well-marked hiking trails, notably the Saint-Nabor loop which passes by the Sainte-Lucie Fountain and the Pagan Wall. This peaceful place, away from the tourist hustle and bustle, is also a starting point for discovering the region, its heritage and its peaceful landscapes. It is steeped in history linked to the nearby Niedermunster monastery, now in ruins, and the presence of medieval remains.
