To my knowledge the Arctic and Anarctic are the only places they haven't had major battles.
What two continents have never been the site of a major military conflict?

Probably Antarctica and Australia. I'm just guessing.

Writeacher is correct. Of the seven continents (North America, South America, Africa, Europe, Asia, Antarctica, and Australia) the last two are the only ones that haven't had major battles.
