Monasteries of nuns belonging to the ancient monastic tradition

13. Monasteries of nuns belonging to the venerable monastic tradition, (⁶³) expressed in the various forms of the contemplative life, when they are entirely devoted to divine worship and live a hidden life within the walls of the monastery, observe papal enclosure; if other activities of service to the People of God are associated with the contemplative life, or if they practice more extensive forms of hospitality in fidelity to the tradition of their Order, their enclosure is defined in their Constitutions. (⁶⁴)

Every monastery or monastic Congregation either follows papal enclosure or defines its own enclosure in its Constitutions, with respect for its specific character.
