There were, however, more overt actions taken that demonstrated to the Anglo-Saxons how different things would be from now on. I am going to give you an example using two pictures.
St. John's Church in Escombe is one of four existing Anglo-Saxon churches in England. Built about 670CE with roughly dressed stones, the nave is 43 feet long and 14 feet wide. Contrast that with the New Romney Church tower of the Church of St. Nicholas. Built mid-12th century, it is a typical Norman church, and towers over any buildings nearby, including any Anglo-Saxon structures. Below you'll see a second photo that gives you a better idea of its size.
During William's reign (1066-1087), in a single generation, at least 15 cathedrals were begun, 13 of which stand today. Imagine the culture shock as the newcomers saw these mammoth structures going up and up, dwarfing their own architectural accomplishments.
Deliberate actions, as I said, but was the reason for the building fervor to intimidate the locals? There are other ways to say "We are in charge" than showing off fine Caen marble from your homeland and saying "We worship God better than you." Why giant cathedrals?
Turns out, William probably had a personal rather than a public reason to make attempts to please God. William was illegitimate (one of his epithets is William the Bastard). That's probably not why he built churches, but it was one reason given initially by Matilda of Flanders for refusing his offer of marriage. She had a better reason for turning him down: their union would violate current laws of consanguinity.
The laws of consanguinity established by the church at that time forbade unions of people within seven generations of relatedness. William was Matilda's third cousin (once removed). We don't know what arguments he used to overcome her objections, but they did marry about 1051, and the flagship he sailed in to England, the Mora, was a gift from Matilda. Some scholars think his building campaign was motivated by appeasing God for all the death caused in the battle for England, for marrying someone to whom he was closely related, and because of a little guilt over taking the throne of England when there was a person who might have had a better claim.
Was everything the Normans built on such a large scale? No. Many defensive structures were not as grand as the churches. Tomorrow let's look at motte-and-bailey.
