In England, Saxon churches still survive in some places, the oldest example being the Church of St Peter-on-the-Wall, Bradwell-on-Sea. But with the Norman conquest, increasingly the new Romanesque churches, often called Norman in England, became the rule. These were massive in relation to the space they enclosed, their walls pierced by windows with semi-circular arches. Internal vaulting used the same shaped arch. Unsupported roofs were never very wide. Yet some of these buildings were huge and of extraordinary beauty. The Abbey church of St. Mary Madgalene at Vézelay in Burgundy and Durham Cathedral in England are two very different examples of this form.
