What is the antonym for haven?

Answer 1

If by sanctuary, you me a "wild life sanctuary" then the antonym is the military term "kill zone" it refers to an abush and means just what it says. The presence or absence of human predation is the key point here. If by sanctuary you mean the space behind the alter in the catholic church, then the antonym would be "prison cell". The space behind the alter in the catholic church has had a legal ststus as an "embassy" as soveriegn soil of the vatican, in European history the power of the King did NOT apply to this place. In sanctuary you are free from the threat of the local law, in a prison cell you are under the burden of the punishment of the law of the land.
