"the appearance of pre-Norman-England-style castle"

"The article notes "giving it the appearance of pre-Norman-England-style castle." Sorry, but I don't think it looks much like any pre-Norman fortification. It could be argued that only the Romans built substantial stone fortifications before the Normans in England, and in a very different style to this. Apart from that, fortifications were built of timber. "Castles" in the medieval sense of the word were introduced to England by the Normans, so I am not sure what the expression "pre-Norman-England-style castle" means? I think this is a romantic expression which needs removing.
