Entrances to Hell

This site has a list of entrances to hell in the UK. I searched the site looking for exactly what he meant by an entrance to hell and found this answer.

Our experts in Europe and doctors in America define an entrance into hell as any access to and from the underworld, found anywhere on the surface of the earth, which is or has been regularly used by Beelzebub and his armies during the last 97 centuries or so.

See, it was more literal than you thought.
