Sea Defences - Norfolk

I am doing an online Landscape Photography course through the WEA and we were challenged to come up with a short project about man's impact on the Landscape.  This image is of the sea wall at Cart Gap, on the east coast of Norfolk.  About a mile away is Happisburgh where the only defences are tons of boulders on the beach.  The cliffs are still slipping slowly into the North Sea. It was a good and challenging afternoon out coming up with images to match the brief.
