Knightsbridge was a hamlet located primarily in the parish of St Margaret (detached) and partly in St Martin in the Fields (the part that later became St George Hanover Square). It also extended into the parishes of Kensington and Chelsea. It was therefore divided between local authorities from a very early time. In the time of Edward I, the manor of Knightsbridge appertained to the abbey of Westminster.It was named after a crossing of the River Westbourne, which is now an underground river. It is recorded that the citizens of London met Matilda of England at the Knight's Bridge in 1141.
