Overview
Charleville Castle sits on the fringe of Tullamore in County Offaly, perched beside the River Clodiagh and surrounded by ancient oak woodland that was once the haunt of Irish druids. Designed by the celebrated architect Francis Johnston in the Gothic‑revival style, the castle is widely regarded as the finest example of its type in Ireland. Its dramatic turrets, pointed arches and intricate plasterwork create a striking silhouette that has attracted filmmakers, festival organisers and, perhaps most famously, ghost hunters.
The castle is managed by the Charleville Castle Heritage Trust, a volunteer‑run charitable organisation. Because the building is still a private family home, visits are by appointment and guided tours are led by knowledgeable volunteers who share both the grand history and the spine‑tingling folklore that surrounds the estate.
History
The site first hosted a modest mansion built by Thomas Moore around 1641. The property passed through the Moore family to Charles William Bury, who was created the 1st Earl of Charleville in 1806. In 1798 Bury commissioned Francis Johnston to design a new house; construction spanned from 1800 to 1812, taking fourteen years to realise the Gothic vision.
Throughout the 19th century the castle played host to literary and social luminaries, most notably Lord Byron, who attended lavish parties in the opulent ballroom. The interior boasts a ceiling designed by William Morris in the dining room and a historic Ladies’ Powder Room where suitors once slipped notes through a paneled door.
Financial difficulties meant the castle was intermittently occupied. It fell into disuse after 1912, and by 1968 the roof had been removed. A series of restoration efforts began in the 1970s, led by Michael McMullen, Constance Heavey Seaquist and Bonnie Vance, and continue today under the stewardship of the Heritage Trust.
In recent decades the castle has diversified its cultural offering. It houses the Explorers’ Museum – a tribute to the explorer Charles Howard‑Bury – and has hosted events such as the Mór Festival, Castlepalooza (2005‑2019), Facefest and a range of theatrical productions. Its atmospheric interiors have also featured in films like Becoming Jane (2007), Northanger Abbey (2007), The Knight Before Christmas (2019) and The Green Knight (2020), as well as the TV series Reign and the 2025 season of Wednesday.
The King Oak and Charleville Forest
One of the most striking natural features on the demesne is the King Oak, a pedunculate oak estimated to be between 400 and 800 years old. Its trunk girth measures 8.29 m and its lower branches stretch up to 27 m. Local legend holds that whenever a branch falls, a member of the Bury family meets an untimely death – a prophecy that seemed to fulfil itself in 1963 when a lightning‑split branch fell and the last surviving Bury, Colonel Charles Howard‑Bury, died weeks later.
The surrounding Charleville Forest is designated a Special Area of Conservation. The ancient oak woodland offers tranquil walks, especially in summer when bluebells carpet the forest floor. The forest is also linked to druidic folklore, adding an extra layer of mystery to the setting. The iconic King Oak has even inspired a local business – the Lynam couple’s handcrafted wood products draw on the tree’s reputation and age.
Walking & Picnic Trails
The demesne’s 24 ha of parkland is criss‑crossed by well‑marked trails suitable for casual strolls and family picnics. Highlights include:
- The Oak Loop – a 1.5 km circuit that passes the King Oak, a small Gothic chapel and remnants of the original 17th‑century walled garden.
- River Clodiagh Walk – a gentle path that follows the riverbank, offering opportunities for bird‑watching and occasional fishing.
- Picnic Meadow – a spacious, level area near the castle’s south gate, ideal for a packed lunch.
Comfortable walking shoes are recommended, and the trail is largely flat, making it suitable for children and older visitors.
What to See & Do
Grand Interiors
The grand staircase, a soaring 220‑year‑old feature, impresses visitors with its carved bannisters and crystal chandeliers.
The ballroom retains its original marble fireplaces and intricate plasterwork, evoking the elegance of 19th‑century aristocratic gatherings.
The Ladies’ Powder Room offers a glimpse into the social customs of the era, while the dining‑room ceiling, designed by William Morris, showcases exquisite decorative art.

The Explorers’ Museum
Located within the castle’s lower wing, the Explorers’ Museum presents artefacts and stories of Irish exploration, focusing on the achievements of Charles Howard‑Bury. Interactive displays make it a rewarding stop for families and history enthusiasts alike.
Haunted Highlights
Charleville Castle’s reputation as Europe’s most haunted building is well‑earned. The most famous spectre is Harriet, a young girl who allegedly fell down the staircase in the 19th century. Visitors often report hearing a faint lullaby or spotting a fleeting silhouette of a child with golden ringlets. The dark nursery wing, the dungeons beneath the main floor, and the ancient King Oak all add to the eerie atmosphere.

Events and Festivals
During the summer months the castle grounds come alive with music festivals such as Castlepalooza (now archived) and Facefest, which blend contemporary performances with the historic setting. Seasonal “fright nights” in October capitalize on the castle’s ghostly lore, offering guided ghost‑hunt tours and storytelling sessions.
Filming & Media Appearances
The castle’s dramatic interiors have made it a favourite location for film and television crews. Recent productions include the Netflix series Wednesday (2025), where the castle doubled as a gothic school, and the feature film The Green Knight (2020). Visitors on guided tours can learn where specific scenes were shot and hear anecdotes from the crew.

The Trust’s news feed shows a lively calendar of cultural activities:
- June 2024 – Chamber Music in the William Morris Room (performed by the Tullamore Gramophone Society & Midlands 103).
