Thriller junkies, add The Guest to your watchlist ASAP.

The first episode of the TV series aired on BBC One and Wales on Monday 1 September at 9pm, with one episode a week airing on Monday evening at 9pm until 22 September. All episodes are also available to watch on BBC iPlayer, if you can’t wait.

Starring Eve Myles and Gabrielle Creevy as leads Fran and Ria, what many of us were left wondering after watching is where was The Guest filmed?

With beautiful locations across Newport, Cardiff and Swansea, the new series joins the ranks of other popular TV series filming in Welsh locations, such as Doctor Who, Tom Hardy’s Havoc and – of course – Gavin and Stacey. In fact, The Guest even shares a few filming locations with the latter!

Here’s everything we know about the series, including all the gorgeous The Guest filming locations.

What is The Guest about?

A plot synopsis from the BBC reads as follows: “Filmed and set in Wales, the four-part drama The Guest is a propulsive, twisting thriller that centres on the intense, toxic relationship between cleaner, Ria, and her mysterious employer, Fran.

As the two women’s lives become intertwined by shared secrets, an obsessive co-dependence emerges that ultimately threatens to become dangerous and manipulative – a psychological game of cat-and-mouse.”

Whitson Court

A lot of the drama unfolds at Maybury Court, Fran and her husband Simon’s rather grand estate, their Manor House and Guest House. It’s almost a character in itself, as its lavish surroundings really highlights Fran’s lavish lifestyle and wealth in comparison to Ria.

Scenes for this were filmed at Whitson Court, which is located near Newport. The building has its own history, as it was once home to German and Jewish refugees during World War Two. It also once hosted a large zoo, Whitson Zoo, during the 1960s and 1970s, belonging to Olive Maybury.

The zoo housed many different creatures – including monkeys, lions and Himalayan bears – and shut down during the 1980s.
