These are pictures of the [Swiss border] (http://www.firstworldwar.com/photos/graphics/gws_gertrenchswiss_01.jpg) and the [Belgian coast] (http://farm9.staticflickr.com/8087/8481825367_48ed4f71ab_z.jpg), where the trenches of the Western Front did in fact come to an end. Of course it should be noted that the construction of the trenches varied based on the topography, terrain and water-table, as I note [here] (https://www.reddit.com/r/AskHistorians/comments/41adfu/wwi_trenches/).
