Three builds, endless adventures

With this 3in1 set, children can start with the grand Medieval Castle and then transform it into either a towering castle with a catapult or a lively marketplace featuring a water mill, guard tower, and prison. Each model reuses many of the same bricks, encouraging planning and experimentation as kids decide how to rebuild the scene.
