I've blogged before about how TV programmes and film locations can be linked to specific landscapes and areas of countryside. I did my degree in what was called 'Last of the Summer Wine' country at the time, and remember seeing it being filmed once. There's also 'Heartbeat' country, near Whitby (I visited the 'Royal' over the winter) and also the impact of 'Game of Thrones'.
The latest programme that people are talking about is Poldark, and there is a useful list of locations on the BBC website.
The local Visit Cornwall site also has some useful information.
Here's one of my images of Cornwall.
