Fortification Clarification?

I’m pretty sure I know the answer to this, but do things like Barrows count as Fortifications, in the case of the Storm Friar attack, or just Fortresses and Villages?


The best way to be sure is if there is a buff on the unit called Fortifications.

Barrows and Mana wells and things normally dont give fortifications, but the Troll Spike Crafter and Dwarf Wall Building Guy can make it so they do.
