Durdle Door is a coastal arch located on the Dorset Coast in the south of England. Durdle Door is formed from a layer of hard limestone standing almost vertically out of the sea. Normally layers of limestone would be horizontal. Only the most fundamental force in geology could have altered these rocks in this way – plate tectonics.
