Marsden Rock, on the left, was a renowned arch formation until in 1996, when the sea finally caused it to collapse. The grotto is a pub/restaurant on the beach, which uses caves under the cliffs and is accessed by a lift from the cliff top. Of course it has a reputation for smugglers and ghosts. The cliffs on this part of the coast are known as 'Leas' and are boulder clay over magnesian limestone. This leads to erosion and the production of what is known as 'sea-stacks' as shown below. Souter lighthouse is  seen in the distance.
