 The name Hellnahellir roughly translates into "The Cave at Caves" – "hellir" meaning "cave" and Hellar being both the name of the farm where Hellnahellir is located and also plural for the word "cave".It will probably never be known for certain how old Hellnahellir really is.Some believe that the cave, or at least some parts of it, was dug out and lived in by Papar, Irish monks who dwelled in Iceland shortly before the Vikings settled in, around the year 900.
