Duncannon Fort is a star-shaped coastal artillery fortification located in southwest County Wexford, strategically positioned on the shores of Waterford Harbour. Commissioned in 1587 by Queen Elizabeth I, the fort was intended to defend the city of Waterford against the looming threat of the Spanish Armada. Its design features massive earthen ramparts and deep ditches, typical of early modern defensive architecture optimized for artillery combat. Throughout its history, the fort played a pivotal role in various military conflicts, most notably during the Irish Confederate Wars and Oliver Cromwell’s siege in 1645. A significant historical detail is that both King James II and King William III departed or arrived in Ireland via this fort during their dynastic struggle for the crown. It remained an active military garrison under British control until 1922, when it was handed over to the Irish Free State. Today, it operates as a heritage site and museum, providing insights into maritime defense history and offering panoramic views of the Suir estuary.
