Westray has traces of a formerly thriving seaweed industry scattered above many of its shores.
These kelp-drying walls are called tangle dykes, which sounds like a 1970’s erotic film to me. Here are the tangle dykes at Grobust, one of my favourite beaches, taken from the air, with the track down to the beach in the centre. The dykes are the short stretches of grey stone wall, enclosing nothing and going nowhere.
I’d love to know what that change in wall direction is all about.
