Born in the castle, 1627
Robert Boyle
The seventh son of the 1st Earl of Cork was born at Lismore Castle in January 1627. He went on to write The Sceptical Chymist in 1661, formulated the gas law that bears his name, and is generally credited with dragging chemistry out of alchemy. He died in London in 1691 and is buried there. The plaque on the bridge is the town's quiet claim on him.
How an English duke ended up with the place
The Devonshires
The Cavendish family came in by marriage in 1753, when Lady Charlotte Boyle married the Marquess of Hartington. The 6th Duke — the "Bachelor Duke" — engaged Joseph Paxton in 1850 and the present castle silhouette is largely Paxton's work, finished in the 1850s with help from his son-in-law and Pugin's panelling. In 1932 Lord Charles Cavendish, second son of the 9th Duke, married Adele Astaire — Fred Astaire's older sister and stage partner — at Chatsworth, and the pair were given Lismore as a wedding present. Adele lived here, on and off, until Charles died in 1944. The current Duke is still the owner.
The Munster planters next door
Spenser, Raleigh, and the river
Edmund Spenser did not live at Lismore — his castle at Kilcolman was over the Knockmealdowns in Cork, near Buttevant — but Sir Walter Raleigh held vast tracts at Lismore and Youghal in the same Munster Plantation, and Spenser was Raleigh's frequent guest. The story that Spenser finished the last verses of The Faerie Queene at Myrtle Grove in Youghal belongs there, not here, but the planters' Munster ran on the Blackwater and Lismore was its hinge.
Two treasures, one walled-up doorway
The Crozier and the Book
In 1814 workmen at Lismore Castle broke through a sealed doorway and found two of medieval Ireland's great objects: the Lismore Crozier — made for a 12th-century bishop of Lismore by a craftsman named Neachtain — and the 15th-century Book of Lismore. The Crozier is in the National Museum in Dublin. The Book of Lismore went to the Cavendishes' English seat at Chatsworth in 1930 and stayed there ninety years, until the trustees gave it to UCC in 2020. Both objects are gone from the town. The doorway is still there.
