Ludwig's Castle is level number 00E and the 4th castle in Super Mario World. The castle is located on Cookie Mountain, next to a hill, and it controls the Twin Bridges area. Ludwig's Castle is also the only level with the layer 2 On/Off switch sprite that makes layer 2 move depending on the On/Off switch's state.
Ludwig's Castle contains three normal rooms, one bonus room, and one boss room. The second room has a layer 2 on/off switch that can control a spiked ceiling. It is the only level that uses this effect. The third room is a climbing net room filled with spikes, and then comes the boss room. You can access the bonus room by finding a pass-through castle brick in the level you start in. Obviously, Ludwig is boss of this castle.
