Monastery (plural: monasteries) denotes the building, or complex of buildings, that houses a room reserved for prayer (e.g. an oratory) as well as the domestic quarters and workplace(s) of monastics, whether monks or nuns, and whether living in community or alone (hermits).
Monasteries may vary greatly in size – a small dwelling accommodating only a hermit, or in the case of communities anything from a single building housing only a one senior and two or three junior monks or nuns, to vast complexes and estates housing tens or hundreds. A monastery complex typically comprises a number of buildings which include a church, dormitory, cloister, refectory, library, balneary and infirmary. Depending on the location, the monastic order and the occupation of its inhabitants, the complex may also include a wide range of buildings that facilitate self-sufficiency and service to the community. These may include a hospice, a school and a range of agricultural and manufacturing buildings such as a barn, a forge or a brewery.
In English usage, the term "monastery" is generally used to denote the buildings of a community of monks. The name convent tends to be used (inaccurately) for the buildings accommodating female monastics (nuns). It may also be used to reflect the Latin usage for houses of friars, more commonly called a friary, or for communities of teaching or nursing Religious Sisters. Various religions may use these terms in more specific ways.
