The Troménie route is marked out by 12 stations marked with 12 granite crosses and 42 small huts where one of our old statues of a saint, carved in wood or stone, comes to shelter in each of them. They have left their church or chapel to come and greet the pilgrims and the relics of Saint Ronan.

The Troménie route is spread over a little more than 12 kilometres through the Porzay plain and the Priory mountain. Its circuit is sacred and it is only open every six years. The days before, where the procession is to pass, the wheat is mown, the corn is cut, the sunken paths are cleared of brambles, improvised bridges are thrown over the streams... Everything is done to allow the crowd of pilgrims to walk along the sacred path.
