On a coastal walk recently we passed through Kimmeridge and saw this 'Nodding Donkey' which is the oldest working oil pump in the UK. Not something you expect in Dorset!!
It is owned by BP and has been pumping oil since 1961. At it's peak it produced 350 barrels a day, but now is down to only 65 barrels a day. Still, no bad going after 56 years!
