The Folsense Museum or Herzen Museum is a location in Professor Layton and the Diabolical Box. It is a museum filled with artifacts and paintings of the Herzen family. The museum was originally funded and created by Mr. Beluga. Grinko is his hired hand and curator for the museum. The museum is located in the center of Folsense and is locked until a certain point in the game. Professor Layton wants to get in so maybe he can find the secrets of the Elysian Box.
