Fawley Oil Refinery map

Situated on the west shore of Southampton Water, Fawley is the largest refinery in the UK, covering some 5 square miles and supplying 15% of the UK's oil products. Refining activity on the site dates back to 1921, with the first main expansion coming in 1951 when Esso brought on stream a new refinery with a capacity of 5.5 million tonnes per year.
