The "Landmür" was an actual dam and served to defend the upper part of the Valais from attacks from the west. The wall attracted the interest of topographers and historians early on. It was first mentioned in land descriptions in 1392. The wall, originally equipped with battlements, battlements and towers, was built around the middle of the 14th century. It has also given rise to a wide variety of speculations. The Perrig Chronicle of 1780 reports on the decay of the stately Letzi. In fact, the wall had been decaying since the 18th century. The Letzi Wall lost its original purpose because the border between the Upper and Lower Valais had shifted down the valley into the Pfyn Forest. It was not until more recent research that the value of this wall was recognised again. Today it is considered by far the best-preserved Letzi wall in the whole of Switzerland. Of the former wall, which was almost 900m long, about 600m are still clearly recognisable. The construction of the wall (around 1350) was a major joint effort by the communities around Brig. The foundation for the preservation of this extraordinary structure was established. The cantonal and federal authorities declared the wall a monument of national importance. In autumn 1996, the first urgent conservation work was carried out.
