Historically, in some Celtic monasteries, abbesses presided over joint-houses of monks and nuns, the most famous example being Saint Brigid of Kildare's leadership in the founding of the monastery at Kildare in Ireland. This custom accompanied Celtic monastic missions to France, Spain, and even to Rome itself. In 1115, Robert, the founder of Fontevraud Abbey near Chinon and Saumur, France, committed the government of the whole order, men as well as women, to a female superior.
