Favourite Hub?

[Adny]

Cistern Entrance would probably be a close second. Although I didn't really think the "Morgue" fitted into it that well; why build a morgue beside a cistern?

Because the cistern is adjacent to the sewers and chancel? Although it is never confirmed, I'm pretty sure the big door in the cistern leads to the the area near the end of the game with the blue torches/giant hub bridge in the middle; and right outside of that area is more prison-y things (torture chambers/holding cells)
