There are a few possibilities: It is some naturally occuring magical mineral; it is the site of an apotheosis; it was raised by an institution (a state, magical society, guild, race, or religion) that still occupies it; it was raised by a long dead institution, and now inhabited by someone else.

 One of these is much more interesting to me because it leaves open more story/idea threads to follow up on. Sure the idea of gods in love is intriguing and lends fable to the atmosphere (whether the inhabitants of the world know it to be true or not) but it doesn't really go anywhere. What other questions are there to ask after establishing a divine relationship?  Adversely, I want to [i]know[/i] why a magical society deemed it necessary to lift an entire continent into the sky. Or what the implications of a mineral that can generate levitation is on society. Is it mined for some use like vehicles or weapons? Is it native to the planet? etc. Just my opinion, discuss!
