I have wanted to visit Durdle Door for years now, and finally made the trek over to Dorset to do so last weekend. We were lucky enough to arrive just as the rain was stopping and the sun poked through the clouds.
Durdle Door itself is a limestone arch jutting out of the cliff face of the Jurassic Coast which stretches through Dorset and Devon. Apparently the name is derived from the Old English world 'thirl' which means bore or drill, and originated as many as 1000 years ago. The arch was formed due to the differing rates of erosion of the different types of rock which make up the surrounding terrain.
