We've been watching Hinterland, a police drama. Where was it filmed?
After a short IMDB and wiki search I came up with, "The programme is set in Aberystwyth, Wales and the three seasons were filmed in and around the town, often in rural locations."
We have been to Wales twice, North Wales in 2013 and South Wales in 2017. The scenery in the show reminds us more of the English Lake District than what we saw in Wales.
We didn't visit the city where the show is filmed, but did come close. After visiting Cardiff and Tenby we visited St. David's Cathedral and a village in Cardiganshire where my surname ancestors came from in 1716. It is about 40 miles SW of the city in the show.
We loved Wales and found many of the people in the rural areas preferred to use the Welsh language instead of English.
We just finished the final episode of Hinterland, which ran from 2016 to 2018. Loved the show.
