Barricade

The Barricade is a structure available in Dungeon Keeper 2. It works similarly to a door when locked, but can be placed on any blank tile you own, allowing you to block off traps and insecurities from your opponents, as well as stopping your own creatures from reaching certain areas. Note that flying creatures can pass over barricades, and creatures can cast spells over them.
Barricades are used well in conjunction with Sentry Traps due to their large range, allowing the sentries plentiful time to bombard your opponents before they can get close.
==Trivia==
*For some reason, the Dungeon Keeper 2 Complete Guide Book shows the icon for the Lair. This is presumably an error.
