In 1951 Lanyon began a series of paintings of the Penwith coastline in west Cornwall, where he had been brought up. The area was already being redefined as a tourist site, but Lanyon resisted the idea that it was a place of only scenic or picturesque attraction.
Here Lanyon conveys a Cornish landscape long defined by economic and industrial activity. The structuring black lines refer to old mine shafts running under the ground and the sea. Just as Paul Nash and other inter-war artists found unexpected visual qualities in electricity pylons, Lanyon also registers a line of telegraph poles.
