Durdle Door (sometimes written Durdle Dor) is a natural limestone arch on the Jurassic Coast near Lulworth in Dorset, England.[1]

It is privately owned by the Welds,[2] a family who owns 12,000 acres (50 km2) in Dorset in the name of the Lulworth Estate.[3] It is open to the public. The name Durdle is derived from the Old English ‘thirl’ meaning bore or drill.[4]
