Cistercian Architecture is a style that emerged in the 12th century, primarily associated with the Cistercian Order, a monastic group founded in France. This architectural style is characterized by simplicity and functionality, reflecting the monks' commitment to a life of austerity. Key features include large, unadorned stone structures, pointed arches, and ribbed vaults, which create a sense of spaciousness and light. The design of Cistercian buildings often emphasizes harmony with nature, incorporating large windows to allow natural light and using local materials. Notable examples include the Abbey of Fontenay and the Abbey of Clairvaux, which showcase the elegance and restraint typical of this architectural movement.
