What is a “cloister”?

Some form of cloister is present in all types of religious life, even the convents of sisters who engage in active apostolates. In such communities, one area of the convent is “cloistered,” reserved for the sisters alone. This type of cloister is called common cloister.

In the contemplative life, the concept of a cloister, a place reserved for the nuns alone, is expanded and deepened. Often the entire monastery is cloistered, and may even be surrounded by a cloister wall. The choir where the nuns sit in the chapel is sometimes hidden from the public who come to pray. And, depending on what form of cloister each monastery professes, some institutes of nuns even make enclosure the object of a fourth vow.

There are three different types of cloister recognized by the Church: papal cloister, constitutional cloister, and monastic cloister, which are explained below.

Papal Cloister

Papal cloister is the strictest form of enclosure, in which a nun does not leave the boundaries of the monastery except for serious reasons. The norms defining papal enclosure are given by Rome. The most recent instruction on papal cloister is the 2018 document Cor Orans, which implements what Pope Francis outlined in his 2016 Apostolic Constitution Vultum Dei Quaerere. Cor Orans states: “The law of papal cloister extends to the dwelling and to all the interior and exterior spaces of the monastery reserved exclusively for the nuns in which the presence of strangers can be admitted only in case of necessity. It must be a space of silence and recollection, facilitated by the absence of external works, where the permanent search for the face of God can develop more easily, according to the Institute’s charism.”

Some of the orders which traditionally practice papal cloister are: Carmelite Nuns, Poor Clares, Dominican Nuns, Visitandines, Holy Spirit Adoration Sisters, and Handmaids of the Precious Blood.

Constitutional Cloister

Constitutional cloister is a form of cloister defined by the norms in the Rule and Constitutions of the individual order. It is generally less strict than papal cloister. This type of cloister is practiced if the community’s charism joins to their life of contemplation some kind of apostolic or charitable work. They are still cloistered nuns, but they may have an apostolate attached to the monastery–such as a retreat house–which would be impossible to carry out if they practiced papal enclosure. Cor Orans says of constitutional cloister: “It must be a space of silence and recollection, where the permanent search for the face of God can develop, according to the charism of the Institute, in consideration of the works of apostolate or charity exercised by the nuns” (n. 205).

Some of the religious orders which traditionally practice constitutional enclosure are: Passionist Nuns, Sisters Adorers of the Precious Blood, and Norbertine Canonesses.
