 The history of Rorà is also characterized (as well as several surrounding municipalities, part of the so-called Waldensian valleys) by the presence of the Waldensians, a religious movement born in the twelfth century in Lyon from the story of Valdo (hence the name), a merchant who abandoned all their own belongings to follow the teaching of Christ.His movement, similar in some ways to the one of St. Francis, was however excommunicated by the Roman Church.In the sixteenth century the Waldensians joined the Protestant Reformation, organizing their communities on the Calvinist model.
