Enter King Edward the Confessor around 1042. He was a very religious guy. He decided to build a massive new abbey in a little village called Westminster.
Westminster was just a muddy island upriver from London. But Edward built his palace right next to the abbey. Suddenly, the king’s business was happening here, not in Winchester.

William the Conqueror: The Clincher
Then came 1066 and William the Conqueror. He didn’t care about Winchester’s history. He cared about control. And to control England, you needed the Thames.
William built the White Tower – the core of the Tower of London. It wasn’t a home. It was a giant stone middle finger to the locals. It screamed, “I’m here, and I’m staying.”
He showed up for his coronation in Westminster Abbey. That sealed the deal. The king was now permanently tied to the London area.
