Spa town in France
Bagnères-de-Luchon , also referred to as Luchon, is a French commune and spa town in the Haute-Garonne departmentin the Occitanie region of south-western France. Bagnères-de-Luchon is located on the Spanish border some 50 km south-west of Saint-Gaudens and 40 km south of Montréjeau at the end of a branch line of the Southern railway at the foot of the central Pyrenees.
Bagnères-de-Luchon is celebrated for its thermal springs. There are 48 springs which vary in composition but are chiefly impregnated with sodium sulphate, and range in temperature from 17 °C to 65 °C. The discovery of numerous Roman remains attests to the antiquity of the baths which are identified with the Onesiorum Thermae of Strabo. Their revival in modern times dates from the latter half of the 18th century, and was due to Antoine Mégret d'Étigny, intendant of Auch.
There is a more modern entrance to the baths next to the older buildings. The bathing experience consists of repeated spells within a hot sulphurous atmosphere in caves that run approximately 100 metres inside the Superbagnères mountain in a cool swimming pool within the entrance building. It was these sulphur springs that led to a twinning of the settlement with Harrogate in 1952.
Bagnères-de-Luchon is celebrated as a fashionable resort. Of the promenades, the finest and most frequented are the Allées d'Étigny, an avenue planted with lime-trees, at the southern extremity of which is the Thermes, or hot baths. The road is lined with bars and restaurants.
