In the Middle Ages, a watchtower stood on the hillock on the present site of the Brignon castle restaurant. Peter II of Savoy, who had authority over the Nendaz region at the time and was in conflict with the Bishop of Sion, decided in 1261 to build a dungeon there to protect the land on the right bank of the Printse. The strategic location made it possible to keep an eye on the valley and to communicate by signals with the Tour de Conthey in the Rhone Valley. The castle was demolished only a few years after its construction for financial reasons. Its ruins can still be seen today.

In the first part of the 20th century, the first hotel in the municipality was built on the ruins of the old tower.

If you are in the area, stop at the Brignon dairy for some tasty cheese and other local products.

In Brignon, at the very bottom of the village, you can also find the start of the Bisse de Baar. To access it, you must pass through the cowshed where you can say 'hi' to its residents.
