The principal places of pilgrimage in the present Diocese of Grenoble are: Notre-Dame de Parménie, near Rivers, re-established in the seventeenth century at the instance of a shepherdess; Notre-Dame de l'Osier, at Vinay, which dates from 1649, and Our Lady of La Salette, which owes its origin to the apparition of the Virgin, 19 September 1846, to Maximin Giraud and Mélanie Calvat, the devotion to Notre-Dame de la Salette being authorized by Bishop Bruillard, 1 May 1852.
