'''{{world|6|fortress}}''' is the third [[fortress]] level and the thirteenth level overall of [[Ice Land]] in ''[[Super Mario Bros. 3]]''.
==Layout==
The fortress has many [[Conveyor Belt|conveyor belt]]s and [[Roto-Disc]]s, many of which are positioned over [[Spike Trap|spikes]]. There are also a couple of [[Boo]]s in the fortress as well. High above the gap between the second Roto-Disc and conveyor belt is a block containing a [[1-Up Mushroom]], which the player can reach if they start the level with a flying power-up and use the straightaway at the start to build the [[P-Meter|Power Meter]]. After the second conveyor belt is a [[? Block]] with a power-up placed between two [[Stretch]]es, with another power-up placed over the third Stretch ahead. The next conveyor belt has a [[Thwomp]] above it, and some [[Coin Block]]s on the platform above the player can reach by flying. After the conveyor belts is a Duo-Roto-Disc placed between two Stretches and over a pit of spikes. After the final jump, there is a door that will drop the player into a room with three Boos. The room's floor will rise, allowing the player to reach a door on the right. Through the door is [[Boom Boom]], in a room with five blocks he will jump between.
