Thiers is a commune in the Puy-de-Dôme department in Auvergne in central France. Thiers is twinned with Bridgnorth, England and Schrobenhausen, Germany. Thiers is built upon a hillside along the Durolle river valley. The steep elevation splits the town into distinct high town and low town areas, with historic half-timbered houses notable in the old quarter of high town.
Thiers is famous for its knives, blades and cutlery industry. The town has a museum in the old quarter, portraying the history of knife-making. Further along the valley, the industrial heritage museum, l'Usine du May, opened in 2009. Modern factories include Forges Gorce who make blades for agricultural machinery from hedge trimmers to combine harvesters, part of McConnel Alamo group.
