Where Was House of the Dragon Season 3 Filmed?

Based on George R. R. Martin’s 2018 book ‘Fire & Blood,’ HBO’s ‘House of the Dragon’ serves as the prequel to ‘Game of Thrones. The fantasy thriller drama series is set nearly two centuries before the events of ‘Game of Thrones’ and centers on the internal succession war within House Targaryen. In season 3 of the Ryan J. Condal and George R.R. Martin creation, Alicent Hightower and Rhaenyra Targaryen decide to join forces after the former makes peace with her in Dragonstone. In exchange for letting Rhaenyra seize the Iron Throne and take Aegon Targaryen’s head, Alicent, her daughter Helaena, and granddaughter Jaehaera get to taste freedom. The political tale unfolds in the fictional Westeros, which turns into a warzone during the civil war between the Targaryens.

House of the Dragon Season 3 Filming Locations

Following the pattern of previous seasons, the production on ‘House of the Dragon’ season 3 once again took place in England and Wales, especially in Hertfordshire, Surrey, Anglesey, Gwynedd, Conwy, and Snowdonia. From what we can tell, principal photography for the third round of the fantasy drama series commenced in April 2025 and continued for about six months before wrapping up in October of the same year.

Spanning about 314 days, the shooting set a record for setting 23 stunt performers on fire simultaneously in a safe and controlled environment. During a conversation with FluxFM, Emma D’Arcy, who portrays Rhaenyra Targaryen, revealed that she had undergone surgery before the shooting began. She stated, “If I’m totally honest, it was a funny time because I had my ACL reconstructed just before we started shooting. And so, I was hopping about on crutches for the first three months in all my frocks.”

Hertfordshire, England

The production team of ‘House of the Dragon’ season 3 returned to the Warner Bros. Studios Leavesden on Warner Drive in Hertfordshire’s Leavesden area to lens most of the indoor sequences set in the Seven Kingdoms. The film studio offers 30 state-of-the-art sound stages of varying sizes, water tanks, over 55 acres of backlot area, prop stores, and 50 workshop spaces. All these amenities make it an ideal filming destination for all kinds of projects.

Surrey, England

Around September 2025, several pivotal sequences for the third iteration of ‘House of the Dragon’ were reportedly taped in the ceremonial county of Surrey. Portions of the Barossa nature reserve and Swinley Forest that lie within Surrey served as prominent production locations for season 3 of the fantasy show. The showrunner, Ryan J. Condal, went on ‘The Stuff Dreams Are Made Of’ podcast and revealed that “things have been going really well.” He added, “We’re doing huge stuff out here in the woods and valleys and fields of Surrey. We’ve built some stuff out here, so I’m really excited.”

Anglesey, Wales

For the purpose of shooting, the filming unit of ‘House of the Dragon’ season 3 also traveled to the island of Anglesey, situated off the north-west coast of Wales. A few beach scenes were shot on Llanddwyn Beach, also known as Newborough Beach, which is a part of a national nature reserve. The Beaumaris Pier was reportedly transformed into a Westeros war zone as numerous intense maritime scenes were shot on location.

Other Locations in Wales

Additional portions for the third season of the Emma D’Arcy starrer were also recorded in other locations across Wales, including Craig Yr Undeb, also known as Union Rock, located on the shore of Llyn Padarn in Gwynedd. In June 2025, the cast and crew members were also spotted taping key scenes at Dinorwig Quarry, situated between the villages of Llanberis and Dinorwig in Gwynedd. Moreover, the walled market town of Conwy and the stunning lake, Ffynon Llugwy, in Snowdonia, feature in various portions.

Jack Sargeant, Minister for Creative, released a statement about how Wales benefits from ‘House of the Dragon’ production. He stated, “This production brings the beauty of North Wales to screens worldwide and further strengthens Wales’s reputation as a leading filming destination. Our investment supports local jobs, skills, and training while delivering significant economic benefits for the region. We’re grateful to HBO for the opportunities created for people in North Wales, particularly those starting careers in TV and film.” Meanwhile, the executive producer, Kevin De La Noy, revealed, “House of the Dragon Cast and Crew were delighted to return to Wales, to a landscape and locale that adds such visual power and vibrant dimension to the storytelling.”
