Yeah, the Anglo-Saxon period was a time of a much less sophisticated building techniques, the UK was an early loss from the Western Rome and the sophistication of the material culture under the Anglo-Saxons there was grim. The Romanesque style of the Normans was largely a continuation and development of late Imperial Roman building traditions (loaded with deliberate callbacks) that grew very sophisticated. That part of the continent had hung onto more of the late Roman engineering traditions that were lost in Britain, so they were able to produce much larger, more impressive buildings, and they had a much richer cultural vocabulary in their iconography and art of their churches as well.
