Ringmahon House

As of the 21st century, the house is owned by Cork City Council and is used as a school by Mahon Youthreach.

[3] The grounds of Ringmahon House contain the former gate tower of an earlier castle.

[4] According to John Windele's Historical and Descriptive Notices of the City of Cork and Its Vicinity (published in 1839), Ringmahon Castle and the surrounding Mahon peninsula take their name from the Irish word rinn (meaning peninsula) and Mahon (a reference to the O'Mahony family who controlled much of the area).

[8][9] James Murphy (1769–1855) built Ringmahon House, to a Georgian design, around 1820.

[3] Mahon Youthreach is funded by the Cork Education and Training Board.
