"Pralognan-la-Vanoise takes its name from ""Pralognan"", formed from the Latin roots pra and longianum: the distant meadow, and ""Vanoise"", perhaps derived from the Celtic vanno which means slope and by extension ""Rock”. The first human traces discovered at Pralognan date back to the Iron Age (5th century BC). It was only in the Middle Ages that a permanent habitat developed. The settlement of Pralognan is linked to the creation of a priory in the 12th century by the monks of Saint-Augustin."
