The Castor Memorial mainly consists of a pair of railway rails welded together to form an X, which are mounted on a piece of track. Underneath the X is a pyramid like those used in some blockade actions.
Behind the X is a signpost showing the distances to various places connected with nuclear facilities and accidents: Krümmel, Fukushima, Wismut, Chernobyl, Asse II and of course Gorleben.
In the background, the Amtsberg with the Waldemar Tower.
