Talk:Wooden Door/@comment-188.81.224.88-20110526194215

As this wiki says mobs cannot open doors if a door is higher than them, so door are useful almost everywhere to prevent mobs to get to you or to cross them. And in dungeons use the pickaxe to remove a line of blocks (4-5 should do it) near the doors (left and right of it), you will need to jump to cross the door, but mobs cannot open it.
