No, Silent Hill is not a real place. The movie version of Silent Hill is actually based on a town in Pennsylvania called Centralia. Apparently, a trash fire accidentally ignited the underground coal deposits in the 60's, and the fires have been burning underneath the town ever since.
There isnt really a canon answer, all we know is that the people that show up there have a lot of guilt in them, and they usually have previous connections with the real silent hill, other than that it's whatever poor fuck gets drawn to the town by whatever weird ghost shit is happening in that particular game.
