Determining the exact location of Silent Hill is complicated. The games portray Silent Hill as a small, secluded town, smothered in fog, surrounded by large hills and flanking a lake, but this could be any one of a hundred towns in the United States. The manual to the first game describes Silent Hill as a small New England resort town, and the town's surroundings, particularly the fog, are similar to the region. In the second game, the number plates on all the cars are from Michigan. The fourth game takes place in a town called Ashfield, which resembles Fall River, Massachusetts, home to famous alleged axe-murderer Lizzie Borden (dark American folklore is one of the series' influences).
