"Many of the stories I have gathered tell how those tribes still protect their own; and even today, March 21, 1916, I have read in the Irish Times that 'a farmer who was summoned by a road contractor for having failed to cut a portion of a hedge on the roadside, told the magistrates at Granard Petty Sessions that he objected to cutting the hedge as it grew in a fort or rath. He however had no objection to the contractor's men cutting the hedge. The magistrate allowed the case to stand til the next court.'"
On the other hand, in 1898 George du Noyer wrote, "At present there is a passage between the fort and the cliff at this end-formed, no doubt, by the removal of the stones by road contractors, and for building purposes. An old man whom I questioned on this point, informed me that he remembered 'hundreds of tons of stones' being taken out of it." (Lynch, P. J.

The authors address the difficulty of understanding the fort's original outline: "The stone rampart as it stands to-day is probably the result of both the original builder's craft and the reconstruction programme undertaken by the Board of Works. Because of the lack of recorded details of this work it is virtually impossible to sort out the original remains from the 1890s reconstructions. The basic difficulty is in deciding whether the rampart was originally straight in plan, as shown by Du Noyer (PI. II) and all other researchers before Deane, or whether its two ends were curved."
T.J. Westropp wrote in 1910, "...something like a panic spread among Irish antiquaries, and the belief was most strongly expressed that the fort had been almost rebuilt, and most of its features altered." (Westropp, Thomas J. "Promontory Forts and Similar Structures in the County Kerry. Part IV. Corcaguiny (The Southern Shore) (Continued)."

The author quotes the fort's excavator as suggesting that the workmen involved in reconstruction work in the 1890's may have mistaken the remains of post-medieval field walls as part of the original rampart, and thus reconstructed the rampart accordingly. The scholars who visited the fort in the nineteenth century all reported the rampart wall as extending in a straight line cliff-to-cliff. In his 1875 Notes on Irish Architecture, Lord Dunraven wrote of Dunbeg, "This great Cyclopean work consists of three ramparts and a massive stone wall, which reaches from cliff to cliff, and cuts off the promontory from
all communication with the mainland." (Dunraven, Edwin Windham Wyndham-Quin. Notes on Irish Architecture By Edwin, Third Earl of Dunraven. Ed. Margaret MacNair Stokes. London: George Bell and Sons, York Street, Covent Garden, 1875. 19.)

⁷Barry 311-312. The clochán has an internal diameter of up to 7.5 m. (24.6 ft). The doorway, which faces north-west, has a height of 1.3 m ( (4.3 ft). In the eastern "guard room," the roof is about 2 m (6.5 ft) above floor level, which would allow a man to stand upright.. However the western chamber is only about 1.2 m (4 ft) high so a man of average height inside would need to crouch or lie prone. The Gallarus Oratory, near the town of Dingle, is an evolved example of the more primitive clochán in Dunbeg Fort and the other nearby clochain in the Fahan area. It can be explored in virtual reality here.

The authors write, "The northern end of the souterrain is marked by a semi-circular wall with a possible small ventilation shaft at roof level...On the balance of probability the souterrain, which lacks any chambers or abrupt changes in floor level, would probably have been a place of refuge for the defenders of the fort. It would have been quite a simple matter to seal off its southernmost entrance inside the rampart with one of the smaller floor slabs of the entrance-way. The last defender into the souterrain would have had to fit this capstone in very tightly between its neighbours so that the souterrain underneath would remain undetected even after the fort had been captured."

There were fragments of post-medieval pottery, nails, and buttons found during the excavation. There were also a few stray finds dating from the nineteenth century, such as fragments of clay pipes and religious medals.
