This specific location can be found in World of Warcraft alpha, behind the gates of Ahn Qiraj, in the open world in Silithus.

This model was later reused for a boss fight in Temple of Ahn Qiraj, with way less pillars.

It reminds me of the Nameless City short story by Lovecraft, which was the mood for that area.

The area surrounding the model is exactly like ingame as well.
