Milton Keynes has the decency to look like it was built in the 1960s and thus isn't particularly creepy. Poundbury was built in the 1980s to Charles's idea of an 'Ideal English Market Town'. Like it was built over centuries. We have plenty of the real deal in Dorset and they are quite nice places with good atmosphere.
Poundbury, by contrast, feels... off. Kinda like Disneyland, but at least Disneyland knows it's artifice? I'm not sure if Poundbury does. It desperately wants to be the real thing. My family drove through it on a sunny day and there were no people on the streets, even though it showed signs of habitation. My in-laws claim they know people who live there. It's like those Stephen King towns where there's a Dark Secret™, except it's not in Maine. I'm pretty sure it eats people.
Also apparently Charles liked to tour it and peek in people's windows to ensure they were living proper Prince of Wales-approved lives. This is not part of the sinister aura of the town, its just another disturbing thing about that place.
yes when i first got the anon and poundbury was described as a new town i assumed it would be a mid-century job like MK! that's what i meant when i said i liked new towns!
but you're totally right, this is a weird georgian mock up as if someone went to bath once and tried to redraw everything from memory but couldn't remember... anything particularly well. i'd say that it's a good setting for a horror film but. it's been done before (you could argue that even don't worry darling plays around with a similar concept)
as for peeking in people's windows...................................... what? if we have any followers living in poundbury please tell us more
