Barricades basically just stand in the way of the minions, causing them time and health (with the reflection enchantment) to break through. However they can also be enchanted with the lighning shield, which stops witches with the lightning enchantment from hitting units behind the wall. You can also use some normal buildings with high hitpoints (card shop, work bench) as a wall, but they are a little less effective and can not be enchanted.
The barricades can be enchanted.
