Place & story

Defending the estuary

Duncannon Fort occupies a rocky promontory on the Wexford shore of Waterford Harbour. Its outer defences cut the headland off from the land, while sea batteries commanded the shipping channel. Construction began in 1587 during fears of Spanish invasion, incorporating an older castle. The fort's later buildings surround a parade ground. A 1611 map and letter by Sir Josias Bodley document improvements including a wider rampart, larger gun platforms and stone reinforcement of the cliffs. [2]

Siege and surrender

During the wars of the 1640s, Duncannon became both a military stronghold and a refuge. In 1645 Confederate forces under Thomas Preston besieged the garrison. A mine opened a breach near the northern sally port, and the defenders surrendered on 19 March. The Confederates retained the fort until the Cromwellian campaigns; it eventually fell in 1650. Its importance came from its command of the estuary, where control of the fort affected the supply and defence of Waterford and New Ross. [2]

The village in 1837

Samuel Lewis counted 560 inhabitants in a village chiefly formed by the street approaching the fort. Fishing and the garrison provided much of its livelihood. The quay exported pigs, butter and poultry and received coal; boats also dredged a substantial oyster bed below the fort. A mail car linked Duncannon with Fethard, Arthurstown and New Ross. Lewis noted a Catholic chapel and two recently built subscription schoolhouses, one of them for infants. [3]

Recovering the gun battery

Archaeological work has revealed how military alterations changed the fort. In 1993 the moat was cleared of material dumped there in the 1940s. Excavation in 1997 concentrated on the lower western battery, an early nineteenth-century position with a magazine and five gun openings. Volunteers removed rubble and exposed two complete gun emplacements, a firing step and a small ammunition store. The investigation also found foundations of a brick side-arms shed shown on an 1858 map. [4] [5]
