If you could pick a raid location from other fiction, what would it be?

Pretty much exactly what the title says, what do you think would be a great raid location from other fictional properties? Factor in atmosphere, aesthetics, a potential story, etc.

For example, my pick would be The Grid from Tron, particularly the grid from Legacy. I think it would tick just about all the boxes. A secret hidden place with a dramatic and beautiful, but at the same time bleak and unsettling atmosphere. An alien and hostile environment with unique aesthetics, lots of potential for environmental storytelling. I feel like the atmosphere would really give me the old D1 raid vibes where you feel isolated. What's more, you could even work it into Destiny's story by having it be some old Golden Age computer with access to old WoMDs that the Vex are trying to access or something.

What are your picks for fictional locations that you think would work well as the setting for a Destiny raid?
