In castle/fortress design, what do you call the wall placed immediately inside the gates that prevents the enemy from having a straight shot into your fortress? (imgur.com)

You see something similar in the entranceway to public bathrooms that don't have doors, where it kind of zig-zags for privacy. I'm trying to figure out what this kind of architectural feature is called. Thanks!

I found a Wikipedia article that expands on motivations for the design: Titulus_(fortification)

The description in the wiki article and the orientation of the diagrams on page 63 of the Keeley document convince me that the ~~more common arrangement was to place the detatched screening wall segment on the exterior of the curtain with an~~ interior version sometimes used either instead of or in addition to the exterior screen.

Edit: I think I read the pg63 diagram orientations wrong, so I think my point is mostly that it can be either inside or outside, and that this whole PDF is really cool.
