The Charterhouse Museum, established in 1993 at the instigation of the monastic community of Serra San Bruno, aims to be a link and connection between monastic life and the world. It is a door that the monks have opened to welcome pilgrims and tourists in a space for reflection and knowledge. An opening through which those who come to Serra San Bruno can access a way of life and a world out of the ordinary. Over nine hundred years, thousands of monks, starting with Saint Bruno, founder of the Carthusian Order, have lived in this place, leaving traces of their silent presence in the environment that hosted them. We find signs of this spirituality of communion in the woods surrounding the monastery, on the paths that saw the Carthusian monks walk during their weekly walks, in the churches and in the religious traditions of this small mountain village.
