How the Sea Carved Dorset's Famous Arch

Durdle Door is a natural limestone arch on Dorset's coast, part of the Jurassic Coast, which became a UNESCO World Heritage Site in 2001. The coast records about 185 million years of Earth history. The name Durdle comes from the Old English word thirl, meaning to pierce or bore.

The arch formed as waves attacked a narrow band of hard Portland limestone, punching a hole through it. Nearby, the sea broke through the same hard rock and scooped out softer clays behind it, creating the almost circular Lulworth Cove. At Stair Hole, rock layers are dramatically folded into the Lulworth Crumple.

Durdle Door and Man O'War Beach are reached by steep paths from the Lulworth Estate, which owns and manages the land. The arch is a favorite photo spot, but people are warned not to jump from it, since jumps have caused serious injuries.
