Upon encountering an old poem ("The Haunted Room" by Emma Marie Caillard, in The Lost Life, and Other Poems, 1889), we thought of this trivia question: What is the haunted mansion within Disneyland's Haunted Mansion, and how many chambers does it have?  The answer is the old attic bride's heart, with four chambers.  In the poem, the heart is not consumed by sorrow but remains unchanged and loving (explaining the Mansion bride's intact organ), home to and haunted by the ghosts of friends who have passed away.
