Calder's Geo, Natural sea cave in Esha Ness, Shetland Islands, Scotland.
Located in the western cliffs, this inlet extends into the coastline with steep rock walls reaching heights of over 20 meters above sea level.
The discovery of this cave's extensive dimensions by geologist Jonathan Swale in recent years changed previous records about Britain's largest natural chambers.
Local maritime traditions and geological research activities regularly bring scientists and explorers to document the features of this natural formation.
Access to the cave requires kayaking equipment and favorable weather conditions, as the chamber opens directly into the North Sea waters.
The cave interior spans approximately 5,600 square meters, making it larger than the Frozen Deep chamber in Somerset's Cheddar Gorge.
