Kinetic Sculpture - Prestonpans, East Lothian

On a family visit today so it's a Prestonpans photograph!  This sculpture was created by Leslie Frank Chorley in 1968.  It's sited by the Firth of Forth from where you can see all the way to Arthur's Seat in Edinburgh.  I've always been drawn to and intrigued by this work.  It's called Kinetic and represents symbols of the coal industry.
