Regarded as Ireland's finest example of Gothic revival architecture, it was built by the Earl of Charleville. However, it is not situated in Co Cork as the name suggests but on the outskirts of Tullamore in the Irish midlands.
Charleville Castle in Tullamore, County Offaly is Ireland's finest gothic revival castle.
It is considered to be Francis Johnston's masterpiece, (he also designed the G.P.O in Dublin) and was built between 1798 and 1810. The massive dining room was designed by Sir William Morris.
