Built between 1822 and 1837 for George Hay Dawkins-Pennant who had inherited the estate, including the previous much smaller castle on the site, on the death of his second cousin, Richard Pennant, whose fortune had been made from Jamaican sugar plantations and local slate quarries. It was designed by Thomas Hopper in mock Norman form, with solid walls and rounded windows and doorways.

In 1951 it was passed to the Treasury in lieu of death duties, which in turn passed it to the National Trust.
