The town's name is entitled in honor to San Remigio. Municipality located at more than 1600 meters altitude, is the last town of the Valle del Gran San Bernardo, on the border with Switzerland. It is composed of the two villages: Saint Rhemy and Bosses, built on the site where a Roman "mansio" was situated, a place where travelers and soldiers would stop at to restore, during their passing through the Alps. Its perfect location on one of the major arterial roads of Europe has seriously influenced its history. Known for the ferruginous water of the source Citrin, which flows from the fountain located in the village square, and the Jambon de Bosses, a culinary specialty to which an annual festival is dedicated. The town is devoted to tourism in Winter with its ski resorts of Crevacol, that feature over 22 miles to Alpine skiing and snowboarding tracks, whilst in Summer, the area offers many hiking trails is of natural interest, such as the Alta Via n.1, or historic interest, such as the Via Francigena.
Between 3000 and 2500 B.C., in the Neolithic period, following the melting of glaciers, the first inhabitants settled in this area by using the pass of Alpis Poenina to trade their goods with the nearby Wallis, inhabited by Veragri. The discovery near the church of Saint Rhémy of skeletons from this period confirm these theories. The area, in prehistoric times, was inhabited by the Salassi (an ancient Celt population) . Even the Romans used this pass as an important access route for the rapid passage of the troops destined for great campaigns and built here soldier camps and shelters. Saint-Rhémy became a "mansio" (border post) called Eudracinum. With the fall of the Roman Empire from the VI to the X century, the territory was ruled by the Huns, the Burgundians, Lombards, Saracens and the Carolingians, who stayed until the X century. To this followed a period of remarkable calm and peace with a strong jurisdiction of the Counts of Savoy.
