Charleville Castle is said to be Francis Johnston's masterpiece.
This beautiful castle, which was left abandoned during a large part of the 20th century (from 1912 until 1970), survived vandalism and onslaughts. In the mezzanine, the main rooms with their spectacular ceilings are now open to visitors. Within the dining room, the ceiling owes its look to the talented William Morris, who stenciled it in the late 1860's.
Charleville Castle can be described as a quite compact building (unlike many gothic rambling castles built by the Victorians) with castellations and towers. Alongside the main part of the building, there are a small gothic chapel, the former kitchen and the stables.
