The Outer Gates are described as a large entrance to the universe. Set in a gigantic wall, between two towers each the size of the Chrysler building, they are powerfully warded, and constantly defended from Outsiders by the Gatekeeper and the immense army of the Winter Court.
In the seriesEdit
In Cold Days, Mother Summer takes Harry Dresden to the Outer Gates so that he could see what was at stake. Dresden sees the huge forces of Winter battle the Outsiders at the Outer Gates. Dresden talks to Rashid, the Gatekeeper, while there.
