At Derrygorman, on the Dingle Peninsula in County Kerry, a souterrain once lay at the centre of a ringfort, yet today there is nothing to see. Souterrains are underground stone-lined passages or chambers, typically associated with early medieval settlements in Ireland, and thought to have served variously as storage spaces, places of refuge, or both. This one has been swallowed entirely by time.

The ringfort at Derrygorman is a roughly circular univallate rath, meaning it was enclosed by a single earthen bank or wall rather than multiple concentric ones. It sits at the south-eastern edge of a flat stretch of ground lying between the Owenascaul river and one of its tributaries, a low and sheltered position typical of early medieval farmstead sites. According to a 1954 reference cited in the Dingle Peninsula archaeological survey compiled by J. Cuppage in 1986, the souterrain was once located at the centre of this enclosure. By the time the survey was published, it was no longer visible, its location presumably disturbed or simply lost to agriculture and the gradual levelling of the land over centuries.
