In Dorset County, England, near Lulworth, lies one of the most amazing rock formations in the world. Something to strange looking that it itself is enough to fill out Dorset hotel rooms even if the sun isn’t shining.

First, a little bit of history. Durdle Door and its beach are part of the Jurassic Coast of Dover, a World Heritage site. Many dinosaur fossils have been discovered and unearthed at this stretch of shoreline, including the first complete Ichthyosaur fossil.

Durdle Door beach itself is privately owned by the same family that owns Lulworth Estate, which also included the beautiful Lulworth castle, that also hosts several medieval related events of great quality. The family, however, is kind enough to leave the beach and the greatest part of their estate open to the general public.

As for Durdle Door itself, it’s something that at first glance defies logic. It indeed looks like a portal at sea, something that can only be explained by a perfect mixture of weak rock and erosion at the exact right place. The existence of that opening was what made the crescent shaped beach next to it possible, and it is now in danger of being destroyed, so efforts are being made to conserve it.
