A Jacobethan exterior wrapped around a Georgian core, with interiors that span three centuries of the Carnarvon family's history.
The castle's distinctive silhouette — corner towers, decorative parapets, and a honey-coloured stone façade — dates to Sir Charles Barry's 1842–1849 rebuild, commissioned by the 3rd Earl of Carnarvon. Barry, working at the same time as his Houses of Parliament project, applied a Jacobethan Revival style: a Victorian reinterpretation of Tudor and Jacobean architectural details rather than a faithful historical copy.
The exterior is faced in Bath stone, which has weathered to the warm golden tone visible today. The four corner towers and the central tower give the building its asymmetrical profile, distinguishing it from the more formally symmetrical country houses built in the same period.
The Saloon is one of the oldest surviving interior spaces, predating Barry's exterior rebuild. Its most distinctive feature is a set of 17th-century Spanish leather wall coverings, hand-tooled and gilded, that have survived multiple changes to the rest of the building around them. The room rises through two storeys with a gallery landing above, and serves as the architectural centre of the state rooms visitors pass through.
The Library houses the family's working book collection across several thousand volumes, with oak shelving original to the room. It's one of the rooms most frequently referenced by visitors and on tours, both for its architectural detail and its appearances on screen.
The Music Room is hung with 16th-century Italian embroideries, considerably older than the room's current architectural shell. The contrast between Renaissance-era textiles and Barry's Victorian joinery is one of the clearer examples of how Highclere's interiors layer different centuries rather than presenting a single unified period style.
Below the state rooms, the castle's original cellars now house the Egyptian Exhibition, a dedicated display connected to the 5th Earl of Carnarvon's funding of the 1922 discovery of Tutankhamun's tomb. The cellar spaces retain their original stone vaulting, giving the exhibition a different architectural character from the State Rooms above — lower ceilings, thicker walls, and a noticeably cooler, enclosed feel. The exhibition is included on the "Castle, Exhibition & Gardens" ticket, not the basic Castle & Gardens admission. Check current ticket types →
The upper floor, accessible via the original staircases, includes the long gallery and a series of bedrooms. Because access requires climbing steep, original Victorian-era staircases, this section is not accessible to visitors using wheelchairs — the ground-floor State Rooms and Egyptian Exhibition remain the accessible route through the building.

The grounds around Highclere were landscaped by Capability Brown in the 18th century, predating Barry's architectural rebuild by roughly a century. The parkland setting — open lawns framed by mature trees rather than formal geometric gardens — reflects Brown's broader naturalistic landscaping style, seen at country estates across England.
