VIDEO: Army find tunnel in Fort Davis

The Defence Forces have made a number of significant archaeological discoveries at a 400-year-old fort in Co Cork and believe they have “only scratched the surface”.

In recent weeks, the army — which runs Fort Davis near Whitegate — uncovered a 100m-long underground tunnel, part of a network beneath the complex at the mouth of Cork Harbour.

On clearing scrubland, they also discovered old ruins and pillboxes along with the remains of torpedo bays in the hewn-out rock at the bottom of the three-level structure, the majority of which is underground.
