"An alternate career path for a woman lay in the Church, where as a nun she escaped the dangers of childbirth. In the convent she could hold any position except that of priest, and as an abbess or prioress she had great power and responsibility."

“Never as neat or well organized as many descriptions suggest, in essence feudalism involved the exchange of grants of land for military and political service, sealed by personal oaths between the lord and the vassal. The castle has been called the perfect architectural expression of the European feudal age.”

“The Church attempted to regulate this rather violent society, and eventually a code of honor evolved known as the code of chivalry. Those who aspired to be knights had to have aristocratic ancestors and wealth enough to own warhorses and armor and to provide for a team of supporters.”

“Stone towers appeared early in the Loire River valley. The massive ruin at Langeais, recently dated 992, was once a broad tower with four corner turrets. Today it stands in the park of a fifteenth-century chateau. Not far off, at Loches, the tower is the earliest surviving great tower to combine within its walls a hall, the lord’s chamber, and a chapel. Recent analysis of the wood used in the original building has dated this tower between 1012 and 1035.”

“Warfare had become endemic in eleventh- and twelfth-century Europe. Castle building used up the resources of the land as every landholder from the king and great nobles to the small landholders fortified their dwellings. Constant skirmishing, brigandage, and open warfare at home and abroad meant that people poured vast resources into training and equipping warriors and building castles and siege machines. The motte and bailey castle with its great tower, as the keep or donjon is called in medieval documents, was admirably suited as a defense against local skirmishes.”

“Whether looming over the land as a symbol of a ruler’s authority or providing a setting for displays of wealth and power in spectacular feasts and tournaments, castles made a visual statement about their owners. All ar chitecture has symbolic overtones, and the castle is a potent image.”

“Chateau Gaillard had utilized the last of the newly built, huge great towers, and Rochester had depended on its early twelfth-century tower. During the course of the thirteenth century defense shifted to a towered wall, the enceinte or enclosure castle. Two plans emerged: the castle could rely on a series of courtyards, which had to be taken one after another, or on a concentric defense in which a second wall entirely surrounded the inner wall.”
