History
''Monasteries were closed religious communities to which particularly devout priests, scholars, and believers withdrew for a life of prayer, study, and service. Monastic life was embraced by several religions, including Christianity and Buddhism. Residents of monasteries became known as monks. In parts of Dark Age Europe, monasteries were the only remaining centers of learning. Irish monks, for example, were instrumental in preserving much ancient knowledge and spreading it back into Europe as the Dark Ages waned. Over time monasteries grew rich in donated land. They became very important local institutions as a source of educated men who could serve as administrators. They also provided health care and emergency relief from their stockpiles of food.''
