A largely rural region of southwestern England, the West Country is referred to in England as “the South” or “the Midwest” might be in the United States. (It includes Cornwall, Devon, and Somerset, according to the NSOED). It was here that the Death Eaters, with the help of at least one giant, caused widespread destruction while attacking Muggles in the summer of 1996. This was one of the things that caused wizarding sentiment to turn against Cornelius Fudge, eventually sacking him as Minister for Magic (HBP1).
Quite a few wizarding places are located in the West Country, including the Burrow and Godric’s Hollow. The West Country also includes Wiltshire, where Malfoy Manor is to be found.
