Rincolisky Castle stands proudly on the southern-shore of Roaringwater Bay, County Cork, Ireland. The castle was originally built in 1495 as a five-storey tower house by the local O'Driscoll clan – occupants of West Cork for many centuries.

Rincolisky was regularly inhabited by an O'Driscoll family, but also served a greater purpose. The castle was used as a watch-tower, controlling the incoming freight at Roaringwater Bay.

In 1602, after standing for well over 100 years, the castle was given to Sir Walter Coppinger, a renowned moneylender with a reputation for ruthlessness, by the invading English forces. Once reposessed, Coppinger changed the name of Rincolisky to Whitehall, after the townland in which it is situated.

The castle remained within the family until the Coppingers lost their possessions in 1690 for their support of James II.

The castle was then transferred to a Samuel Townsend. The Townsend family removed the three upper floors of the castle to provide building material for their new mansion house; Whitehall House. What remained of Rincolisky Castle, just 2 storeys, was left to ruin for over three centuries.

It is rumoured that there is a tunnel leading from Rincolisky Castle to Whitehall House. One of the Townsends is said to have sent his page boy down the passage to see if it was clear. The boy was never seen again.

In 2000 the castle's current owner, Stefanie Jaax, restored the ivy-clad ruins of Rincolisky and now markets the property as an Irish self-catering castle.
