The northern tripoint area is consisting from two technical tripoints and one triline area. The western technical tripoint – DELUFRLU – where the middlepoint of the France – Luxembourg River Mosel meets the condominium. The eastern technical tripoint – DEDELUFR – is the point where the condominium meets both the border of France and the border of Germany. The line between these two technical tripoints forms the actual triline boundary – DEFRLU – between the the common area of Germany and Luxembourg in north and France in south. This line is about 114 metres long, whereof about 29 m are on dry land, and stops in both ends one single point before both tripoints.  (Image: Le Géoportail National)
