Castlecore is the Latest Trend Dominating Interior Design

Google searches for Castlecore have risen by 1,957% over the last year, with nearly 11k posts on Instagram citing the hashtag. Castlecore has been steadily building for years, largely due to historical dramas putting the theme in the spotlight.

Television is Serving as a Source of Inspiration

Game of Thrones helped to bring medieval-inspired settings into mainstream media. Towering castles, iron chandeliers, and carved furniture all have a strong visual identity in the show. In the prequel, House of the Dragon, the aesthetic is firmly cemented, introducing a new generation of people to medieval architecture.

The Traitors has also been another influence. The show is inside a dramatic castle with oak furniture, candlelit rooms, and a roaring fireplace. The atmospheric setting has helped to inspire fortress-like interiors.

Books like The Once and Future King also put the focus on the period. Kings, Queens, and Jacks originated from royal courts in the medieval era, and today, decorative card decks feature them as icons and are still instantly recognisable.

This is especially the case in iGaming. People who play casino games online will notice that games like Jacks or Better feature knights and royalty, which is a throwback to the armour people wore to give themselves protection when in battle.

When breaking down the inspiration out there, it’s not hard to see how trends like this are inspiring today’s aesthetics, and how the shift away from minimalism is taking a dramatic turn.

Castlecore is Causing a Popularity Surge in Permanent Furniture

Castlecore reflects a lot of changing tastes. For years, people have been focusing on white walls and flat-pack furniture. Now, homeowners are looking for more permanent fixtures, such as reclaimed timber, carved oak, and natural stone. Wrought iron is making a comeback, as is candlelight and unlacquered brass.

Another defining feature of castlecore would be texture. Rather than opting for a glossy finish, homeowners are now getting weathered wood, handmade tiles, or rough-cut stone. This is again a wider move away from disposable interiors, while adopting more natural and sustainable materials.

On social media, millions of people share gothic bedrooms and dining rooms, using hashtags like #MedievalModern and #GothicHome.

Rather than following historical accuracy, Castlecore in 2026 is more focused on creating homes that have craftsmanship as well as personality. One of the best things about Castlecore is that it can even be embraced by those who are on a budget.

Faux-stone walls can be created by using textured wallpaper, and vintage furniture can be upcycled to create unique pieces without spending a fortune. As upcycling is a huge trend right now, this movement complements it perfectly, which is another reason for its rise in popularity.

Interestingly, Travelista has reported that Google searches for Castlecore rose by 2,000% at the start of the year, and more people are choosing to stay at iconic castles across Europe.

Traffic from the US to Europe is spiking right now too, showing that medieval media and trends aren’t just inspiring home decor; they’re having a big impact on people’s lifestyle choices.
