Wintergrasp Fortress is the primary objective for control of the Wintergrasp region. The fortress has two layers of walls — the outer wall with the fortress gates, and the inner wall protecting the keep. The fortress also has a siege workshop for the construction of siege weapons for the defense of the fortress, quest-givers, the Wintergrasp quartermaster, and the entrance to the Vault of Archavon.
Atop a tower in the south-west corner of the innermost courtyard there is a room seemingly magical in nature. It seems to serve no purpose besides providing a hiding place.
