Today’s Knightsbridge, the wealthy shoppers’ paradise, is a recent cross-border development. This book breaks new ground by uncovering an earlier, larger Knightsbridge and showing why its initial extent and history have been largely forgotten. Knightsbridge was the southern part of the Westminster abbey manor of Knightsbridge and Westbourne, and until 1900 covered the same area as the parish of St Margaret Westminster Detached. Pre-1900 Knightsbridge/Westminster included today’s Kensington Palace, Kensington Gardens, almost half of ‘South Kensington’, and Hyde Park west of the Serpentine (or river Westbourne). So why was so much of Knightsbridge lost to memory, becoming thought of only in terms of Westminster, Hyde or (until 1900 entirely wrongly) Kensington?
