1. It Wasn’t Intended to Be a Royal Residence
When William the Conqueror originally built Windsor Castle in the late 11th century, it was intended as a fortress. William erected the castle to oversee a strategic part of the River Thames, and to help protect Norman dominance around London. The royals of the time lived in the former palace of Edward the Confessor in the village of Old Windsor. In 1110, Henry I became the first royal to use the castle as a residence.
