A castle was built at Carrignavar by Donal or Daniel McCarthy, younger brother of the first Viscount Muskerry, of the MacCarthy of Muskerry family.[5][6] It was said to have been the last fortress in Munster to fall to Cromwell.[7] His descendants (surname variously spelt McCarty or McCartie) lived there into the nineteenth century,[6][8][9] though, by 1840, little more than a square tower remained.[7] In the eighteenth century, Charles MacCarthy was a Jacobite sympathiser and patron of late Gaelic poetry; he and his poets converted, at least in form, from Roman Catholicism to the Anglican Church of Ireland to escape the Penal Laws.[10]
Carrignavar House, a castellated country house, was built beside the castle ruins in the late nineteenth century.[8] John Sheedy bought it in the early twentieth century and later sold it to the Sacred Heart Fathers, who opened Sacred Heart College (Irish: Coláiste an Chroí Naofa) secondary school there in 1950.[8][11]
