Utgard Castle (Anime)

Utgard Castle (ウトガルド城) is an abandoned castle located within Wall Rose, close to its perimeter.

Structure
The castle's first protection is a small set of walls that now are almost destroyed. After them, a pentagonal shaped wall surrounds all the structure. These walls have squared-shaped battlements over them. When the Scouts arrive, at least two of the five walls are completely broken.

Inside the walls there is an empty courtyard with a small stable, two doors that communicate the interior part of the castle with the exterior and a stair that communicates the ground with the walls and the base of the towers.

The towers are the most prominent feature. They are the tallest part of the castle and connected by a small bridge. One of them is broader and taller than the other, and has the same battlement that the pentagonal walls do. The other is thinner and smaller, and its top part is destroyed when the Scouts find it.

Clash of the Titans arc
The castle is first discovered when two squads from the scouts come across each other while searching for the breach in Wall Rose. The decision is made to take refugee within the nearby castle, and rest until morning before resuming their patrol. The group includes senior members Nanaba, Gelgar, Henning, and Lynne as well as several rookie members under their command - Bertholdt Hoover, Reiner Braun, Conny Springer, Christa Lenz and Ymir.

The group gathers in an intact room, and attempt to get some rest while things are quiet. The senior officers set up a watch on top of the tower, and prepare for a long night. Some time later, the castle comes under attack by Titans able to function normally during night. As the group gather on the tower, they spot the beast-like abnormal Titan walking past the castle and climbing Wall Rose.
