The cavern must have been open to the Irish Sea back in the 16th century, because according to one of Salty's tales, Captain Calles literally "sailed" into the cavern. The cavern was used by the pirate to hide his pirate ship when the merchant ships and the navy tried to track him down. Captain Calles never retrieved his ship; yet there was also the possibility that the navy did not call off the search until Captain Calles' death. The cove entrance collapsed at one point, causing the pirate ship to stay there undisturbed for over 400 years.
