Place & story

The castle above the Awbeg

Blackwater Castle was a seat of the Roche family. In 1650, Lord Broghill's forces bombarded it and the garrison surrendered. The Roche lands were confiscated and granted to John Widenham, whose family retained the property into the twentieth century. The later name Castle Widenham records that change of ownership. [2]

The Book of Fermoy

The Roche family supported the production of the manuscript known as the Book of Fermoy. It contains genealogy, poetry and narrative material associated with their circle, alongside other texts brought together in the surviving volume. The Irish Script on Screen catalogue identifies the manuscript as Royal Irish Academy MS 23 E 29 and dates most of it to the fifteenth century. This material links the castle with scribes and literary patronage, extending its history beyond defence and the control of surrounding estates. [3] [4]

Folklore & tradition

Stories about the sheela-na-gig

A carved sheela-na-gig associated with the castle has been recorded in several locations, including beside the river, near a holy well and within the castle grounds. The castle's heritage account also records a local story that the stone was cast into the river to rid a household of bad luck. Its authors explicitly state that they cannot establish when, or whether, this happened. The distinction is useful: the figure's changing recorded locations belong to its material history, while the explanation involving misfortune remains an unverified local legend. [3]
