The Layton Museum is a feature of Layton's Mystery Journey: Katrielle and the Millionaires' Conspiracy. In the museum, the player is able to unlock various pieces of artwork from previous Professor Layton titles.
All of the artwork can be bought for 100 points a piece, or for 80 points in the Deluxe Edition of the game. These points are gained by solving the daily puzzles of the game, each puzzle giving out 15 points, with the exception for the puzzle Fruit Farce 22, which is worth 30 points.
