A suburb of Bracknell is Martins Heron (which seems rather often to show up in these Quizzes and Games). In the Harry Potter films, the scenes in Little Whinging in suburban Surrey (where Harry lives, reluctantly, with his odious relatives the Dursleys), were filmed in Martins Heron: which some fans regard as being actually, per "canon", a disguised version of Martins Heron. A real settlement which features in genuine Potter lore, endorsed by the author -- is Hampstead Garden Suburb, London Borough of Barnet: where Hermione Granger lives with her (non-magical) parents.
