The Benedictine Williamites, more often known by the name of its chief house, Territorial Abbey of Montevergine in central Italy, was a Catholic monastic order.
[1] Besides Monte Vergine, St. William of Vercelli founded a considerable number of monasteries, especially in the Kingdom of Naples, including a double monastery for men and women at Goleto (near Nusco).
Pope Celestine III confirmed the congregation by a bull (4 November 1197).
The community at Monte Vergine retains the white colour of the habit, which is in other respects like that of the Benedictines.
The habit was white with a black veil, and their rule very severe in the matter of fasting and abstinence.
