Pillars are large, indestructible columns found in Super Mario World, New Super Mario Bros., and New Super Mario Bros. Wii. These obstacles appear mostly in fortresses, towers, and castles, usually hidden in the floor, ceiling, or also in walls. They move slowly for some seconds, revealing themselves, before suddenly smashing almost anything on their way. After some seconds later, pillars move slowly back.
There are many types of pillars. Some are just large columns with a flat end that fall on the player, these are the ones known as the "smasher". These can be avoided by hiding in small pits found under the pillars. There are also Spikes and Skewers.
If pillars have spikes, Mario may take damage, changing into small form, losing a life, or reverts to Super Mario, except in Super Mario World (SNES version), where the player reverts to small form.
- Smithy uses a special attack, the Sledge, which lets fall a pillar over his target.
