Ruperra Castle at 400: History, Ruins and 2026 Events
On this page
Ruperra Castle turns 400 in 2026. The roofless landmark near Caerphilly was completed in 1626 as a sophisticated Jacobean country house disguised as a castle, with a square plan, four round corner towers and battlements. Today it is a nationally important ruin at risk of further collapse.
A free three-day anniversary exhibition runs from 15 to 17 October 2026 at Bedwas Workmen's Hall. This guide explains what a "pageant castle" is, how Ruperra changed over four centuries and how to attend the commemoration without mistaking it for access to the unsafe castle site.

Why Ruperra looks like a castle
Ruperra is not a medieval fortress. Cadw describes it as a rare Jacobean Renaissance mock castle, built when elite houses could borrow the drama of towers and battlements without being designed for medieval warfare. Its appearance belongs to a courtly taste for chivalry, spectacle and carefully staged architecture.
The Ruperra Castle Preservation Trust calls it Wales's only pageant castle. In this context, "pageant" points to the temporary castle scenery used in Tudor and Jacobean celebrations. Ruperra turned that theatrical idea into a permanent country house. The result mixed deliberately old-fashioned Gothic details with Renaissance planning and decoration.
Cadw compares its compact square form and corner towers with Wollaton Hall in Nottinghamshire and Lulworth Castle in Dorset. Brick was used extensively in the original structure, an unusually early choice in Glamorgan.
Who built Ruperra Castle?
Sir Thomas Morgan of Machen built the house around 1626. Cadw records him as steward to the Earl of Pembroke, placing Ruperra within the world of wealthy court officials rather than border warfare. The building's sophistication was exceptional in Wales at the time.
King Charles I stayed at Ruperra in 1645 after the Battle of Naseby. The Cadw list description records that it was considered one of the few houses fit for a king. That episode gives the theatrical building a brief place in the political history of the Civil War.
Fire, rebuilding and the road to ruin
A fire badly damaged the castle in 1785. Architect Thomas Hardwick directed its reconstruction, replacing the gables between the towers with the battlemented parapets visible in later images. The rebuilding made the house look even more overtly castellated.
The Morgan family increasingly centred its life at Tredegar House, while Ruperra was used by heirs and later occupied less regularly. Early twentieth-century additions included new east and west porches, but the house's long decline had begun.

In December 1941, while British troops were stationed there, another accidental fire gutted the building. It was left roofless. Part of the south-east tower collapsed in 1982, and the monument remains vulnerable. Coflein describes the surviving structure as a burnt-out shell retaining evidence of its hall, screens passage, kitchens and service rooms.
The landscape matters too
Ruperra is more than one building. Cadw's historic park and garden register covers the remains of a deer park, formal gardens, pleasure grounds and a hilltop mount once crowned by a summerhouse. It describes the castle and landscape as an exceptional group.
The design evolved over several periods, from seventeenth-century formal planning to Edwardian gardens and landscaping. A surviving glasshouse is part of that later story. This wider setting helps explain why conservationists discuss the castle as a historic landscape rather than an isolated ruin.
The Welsh name Castell Rhiw'r Perrai is used by the preservation trust alongside Ruperra Castle. Its anniversary programme translates Rhiw'r Perrai as "the slope of the pear trees".
What is happening for the 400th anniversary?
The Ruperra Castle Preservation Trust is holding a free exhibition from 1pm to 6pm on Thursday 15, Friday 16 and Saturday 17 October 2026. The venue is Bedwas Workmen's Hall, Old Newport Road, Caerphilly CF83 8BJ. Visitors can simply turn up for the exhibition, while the separate free talks and performances require booking.

Thursday's programme includes a 2pm talk about the restoration of Ruperra's architectural relative, Lulworth Castle, followed by a 4pm wildlife talk. Friday includes an 11am Morgan-family talk at Lower Machen Church, so check the venue carefully when booking.
Saturday explores the first castle, the meaning of Rhiw'r Perrai, historic pageants and courtly dancing. The official event page has the latest booking links and should be checked before travelling.
Important location note
The commemoration is at Bedwas Workmen's Hall, not inside Ruperra Castle. Cadw locates the ruin beyond a private drive, and the preservation trust says it is at risk of collapse. Do not treat this event listing as permission to enter the castle or its grounds.
Is Ruperra Castle open to visitors?
The official anniversary notice does not advertise public access to the castle. The safest way to engage with Ruperra in October is through the exhibition, booked talks and preservation trust material. Any future access arrangement should be confirmed directly with the relevant organiser rather than inferred from photographs or map routes.
This distinction is important because historic ruins can look stable from a distance while containing unsupported masonry, hidden drops and unsafe interiors. The building's Grade II* and scheduled status also means it is legally protected.
Why the 400th anniversary matters
Ruperra's survival makes several chapters of Welsh history visible at once: Jacobean ambition, courtly design, Civil War politics, great-estate life, changing garden fashions, wartime occupation and the difficult conservation of a roofless ruin.
The anniversary is also a chance to replace a simple "abandoned castle" story with a more accurate one. Ruperra was a Renaissance house performing the role of a castle. Its value lies in that unusual architectural idea, the landscape around it and the evidence still held within its walls.
Conservation is therefore about more than reconstructing a picturesque facade. Archaeologists and building historians can read different phases in the masonry, openings and surviving rooms. Stabilising what remains would protect that evidence while allowing the building's fires, alterations and losses to stay legible.
The page has a modest but steady international audience: the English Wikipedia article recorded 65,577 views across 2016 to 2025. October averaged slightly fewer views than the typical month, so the 2026 event is a specific anniversary catalyst rather than proof of a recurring seasonal search peak.
