A 19th-century solid lead artillery shell is to go on display at Collins Barracks Military Museum in Dublin after it was discovered by a woman and her daughter while gardening at the weekend.
Pensioner Ms Sarah White and her daughter, Ms Valerie Williams, were working on a flower bed at Ms White's home at Wilton Lawn in Cork on Saturday when they found the shell, which measures 20 inches long and four inches in diameter.
"Our explosives ordinance team examined the shell and assessed that it was safe before bringing it back to Collins Barracks. We believe it dates from the 1860s," said the press officer for Collins Barracks, Capt Dan Harvey.
"It's solid lead and weighs four stone so it's quite heavy. We think it was used in coastal defences such as Charles Fort in Kinsale, but we're puzzled as to how it ended up in Wilton."
