Where Was The Ballad of Wallis Island Filmed?
Despite being set on a remote island, The Ballad of Wallis Island was filmed primarily along the coast of Wales. The filmmakers used real coastal landscapes to create the illusion of an isolated setting.

The house represents Charles’s home in the film is situated in a town where director James Griffiths’s mother was born and lived. The choice of location adds a personal and emotional connection to the film, as Griffiths’s family has strong ties to the area.
A difficult-to-access beach along the Welsh coast was used for certain scenes. The secluded nature of the beach helped sell the illusion of Charles’s home being on a faraway island, even though the movie was filmed on the mainland.

The location in the above image is Ramsey Island, a nature reserve owned and managed by the Royal Society for the Protection of Birds (RSPB). Located off the coast of Pembrokeshire, Wales, about 1 km (0.6 miles) west of St. David’s Head, Ramsey Island provided stunning natural scenery that enhanced the film’s sense of isolation.
