Norman Cathedrals are a style of church architecture that emerged in the 11th century, primarily in Normandy, France. Characterized by their massive stone structures, rounded arches, and thick walls, these cathedrals reflect the Romanesque architectural style. They often feature intricate carvings and large towers, showcasing the power and influence of the Norman culture during this period. One of the most famous examples of a Norman Cathedral is the Bayeux Cathedral, which was built in the 11th century and is known for its stunning stained glass and historical significance. These cathedrals played a crucial role in the spread of Christianity and the establishment of ecclesiastical authority in medieval Europe.
