Rincolisky Castle, sometimes also called Whitehall Castle, lies on a hill on the southern shore or Roaringwater Bay, in County Cork in Ireland.
Rincolisky Castle, originally a 5 storey high, square tower house was built in 1495 by the powerful local O'Driscoll clan.
In 1602, after the Battle of Kinsale, the castle was easily taken by English forces. It was then given to Sir Walter Coppinger. He changed the name of the castle into Whitehall, after the townland in which it is situated. The Coppingers lost their possessions in 1690 for supporting James II.
It was then given to Samuel Townsend. The Townsends built a new mansion nearby; Whitehall House. They removed the 3 upper floors of Rincolisky Castle to provide building material for their new mansion. From then on the truncated 2 storeys high remnant of Rincolisky Castle fell to ruin. It is said that there is a tunnel leading from the castle to the mansion. One of the Townsends sent his little page boy down the passage to see if it was clear. The boy was never seen again.
In 2000, the ivy covered ruin of Rincolisky Castle was restored and made habitable again.
