Hospitalité Notre Dame de Lourdes
The Hospitalité Notre Dame de Lourdes (HNDL) is a Roman Catholic religious confraternity under the spiritual authority of the Bishop of Tarbes and Lourdes, and works closely with the Rector of the Sanctuaries and his pastoral team. Hospitalités were originally Catholic charitable organisations which welcomed and sheltered travellers, particularly those in need; in the 2020s, HNDL is the central co-ordinating Hospitalité for pilgrims to the Sanctuary of Our Lady of Lourdes, organising the reception of pilgrims, training of volunteers, crowd-control and other needs.
