Puerta dura

The picturesque natural stone arch is located on the wild, pebble beach that is part of the Jurassic Coast, a UNESCO World Heritage Site. It was formed by the action of sea water on rocks, most likely 140 million years ago in the Jurassic period. There are many caves in the rocks surrounding the cliff, but entry to them is prohibited.

There is a steep path down the cliff leading to the arch. It is ended with narrow steps consisting of 143 steps. The road from the nearest parking lot takes about 30 minutes. It is worth bearing in mind that there are no amenities on the beach next to the arch. You can bathe here, but the place is not guarded by lifeguards, so be careful.

The name of the bow is most likely derived from the Old English word thirl which means drill or drill. It is believed that this name already existed in the Middle Ages.
