Passy has four churches on its territory.
The oldest, St-Pierre et St-Paul de Passy, is linked to the great agro-pastoral tradition of the region, St-Joseph de Chedde to the industrial past of the site and N.-D.-de-Toute-Grâce to the climatic spa of the Plateau d’Assy. Finally, St Donat des Plagnes. Four eras, four different visions not to be missed in order to understand the passerand territory in all its diversity. Note that the commune still has a dozen chapels, some in the Baroque style, others in the former sanatoriums.
