Perhaps the beginning of another cove, where gaps have been eroded in the harder rock and the softer rock behind has then been eroded quickly.
Another cove further down the coastline. The rocks in the sea are resistant Purbeck limestone.
Two conjoined semi-circular coves. You can see the diffracted waves which echo the shape of the cove, and also the remnants of the band of resistant rock in the sea that would have once stretched the whole length of the coastline.
Durdle Door, slightly further along the coastline.
