Door

Doors are blocks that are only obtainable through crafting. Upon clicking the object with either the left or right mouse button the block will shift from its native closed state to an open state allowing passage; clicking the door once more will return it to being a closed door. If two wooden doors are placed adjacent to each other, they will orient with their handles inward.

- Doors can take quite a bit of time to destroy. To destroy them more quickly, simply destroy the block beneath the door.

Iron Doors
An Iron Door acts the same as a wooden door with the exception of only being able to be toggled by a switching mechanism such as a Lever or a Stone Button. This creates the possibility to make doors that are only controllable from remote locations using a switch and Redstone.

Glitches
Because the door occupies the edge of a tile, if you stand in the center of the tile you can hit things on the other side. Make sure you place the door from the outside of your house so that you can attack monsters on the other side, but they cannot attack you. As long as you follow this rule and make sure the door is on the edge that will be exposed to danger, monsters cannot harm you from the outside, but you can fight them without opening the door.

Minecarts will not move through doors. Water won't either, leading to an excellent way to keep multiple rooms from flooding. Another practical use of the door's water glitch is to leave a door open as an entrance to something underwater that is water-free on the other side.

Doors may be placed on doors, but it will be lost, and nothing will happen.
