Double monastery

A double monastery (also double house) is a monastery combining a separate community of monks and one of nuns, joined in one institution. More common in the monasticism of Eastern Christianity, where they are found since the 4th century, in the West the establishment of double monasteries became popular after Columbanus and were found in Anglo-Saxon England and Gaul. Double monasteries were forbidden by the Second Council of Nicaea in 787, though it took many years for the decree to be enforced. In a significantly different way, double monasteries were revived again after the 12th century, when a number of religious houses were established on this pattern, among Benedictines and possibly the Dominicans. The 14th-century Bridgittines were consciously founded using this form of community.
