Durdle Door

Durdle Door is a natural limestone arch on the Jurassic Coast in Dorset, England. The arch has formed because less resitant rock, including clay and greensand have been eroded, leaving a headland of the more resistant Portland limestone. This headland has been eroded leaving a natural arch.

Durdle Door is a popualr tourist "honeypot", as it is a short walk from the equally popular Lulworth Cove, and lies on the South West Coast Path.
