Here's a thought, maybe that's why it was never completed. Maybe after putting so much work into it someone said to the Stonemason "Well it is lovely and all, but just how the F*** do you plan to get it out of here"?
If it is the one I am thinking of, it cracked when it was maybe 80% completed.
Nothing they could do but abandon it and all that work.
“...but just how the F*** do you plan to get it out of here”?
Well, if they had been just a little more careful, and not broken the bottle that contained the obelisk, they could have rolled it out of the quarry.

That made me laugh, and it is too early in the morning here to actually be happy.
But I can see it in my minds eye. “How do you plan to get it out of here?”
