History and Fossils

Kimmeridge Bay forms part of the Jurassic Coast, a World Heritage Site known for its geological history stretching back over 150 million years. The layers of rock exposed along the shoreline were formed during the Late Jurassic period, when this area lay beneath a shallow sea.

The flat stone ledges seen at low tide are part of the Kimmeridge Clay formation, rich in organic material and shaped slowly over time. These rocks have long been studied for the fossils they contain, including ammonites, marine reptiles and other remains of ancient sea life.

Fragments can still be found along the shore, revealed by the movement of the tide and the gradual erosion of the cliffs. The landscape feels shaped not only by the present sea, but by a much older one that existed long before.

This sense of time and change is part of what gives the place its atmosphere — quiet, expansive, and deeply rooted in the past.

Wartime History

During the Second World War, Kimmeridge Bay and the surrounding coastline were used for military training. The wide, open ledges and secluded setting made it suitable for exercises preparing troops for coastal landings.

Remains of this period can still be found in the landscape. Small concrete structures and observation points are scattered across the area, quietly marking its role in wartime activity.

The coastline would have felt very different then — not a place of stillness, but one of preparation and uncertainty. Yet over time, the sea and weather have softened these traces, leaving them as part of the wider story of the place.

Today, they sit quietly within the landscape, a reminder of a different chapter held within the same stretch of coast.
