You can see a really good set of paleocontinental reconstructions at:
And while the exact point in Antarctica which is currently at the South
Pole hasn't always been there, the landmass itself (with other masses
connected to if for most of this time) has occupied a generally southern
polar position for at least 600 million years.
(There have been times, for instance, when rocks currently in southern
Africa rather than Antarctica were at the exact South Pole, but the rocks
of Antarctica were still deep down south of the paleo-tropics.)
