Harry Potter: Hogwarts Chamber of Secrets

Below the plumbing and behind a hiss no one wanted to hear, the oldest secret of Poudlard waits to be found. This 1,172-piece set opens from a candlelit corridor down into the chamber itself, complete with a serpent statue and the long shadow of something coiled. Eleven minifigures share the descent, though only the bravest of them means to go all the way down.
