Where does the name Serre Chevalier come from?

A valley as steeped in history as the Guisane did not need to ask a designer to draw a symbol for its resort. It is thanks to the local heritage that the resort has been able to unite its villages behind the banner of the crowned eagle, which appears on the coat of arms of the Borel family of the hamlet of Le Bez. As for the name of Serre Chevalier, it comes from : "Serre" which means a hillock (in patois a small mountain) and "chevalier" a ravine dug by a torrent.
