Cistercien (Cistercians)

Monastic order founded in and named after Cîteaux.
One of the great abbots of this order was Bernard of Clairvaux.
The Cistercian monks are also referred to as white monks because of the colour of their habit.
The order follows the rules of Saint-Benedict, although strictly speaking they are not a bénédictin (Benedictine) Order.
Sobriety and simplicity are characteristic for Cistercian monastères (monasteries), and most monasteries of this order have a similar lay-out.
The coat of arms comes from Wikipedia.
