1999 A reinforced concrete mock-up of an anti-invasion Atlantic Wall anti-tank wall. It is situated within the Whitestone Range to the E of the public road across Sheriff Muir. The wall is 86m in length from NE to SW and stands to about 3m in height. Just over half of the length of the wall is 3m thick, stepping down to 0.
7m at the SW end, where the wall curves round slightly to the W. The rear face of the wall is vertical for about half its height, battering inwards towards the top, along which there are iron pickets to carry barbed wire. The corrugations of the shuttering used in the construction of the wall are clearly visible, as are individual dumps of concrete.
Some care has been taken in finishing off the surfaces where initial dumping of concrete has left gaps. A tunnel, 0. 6m wide, runs through the wall about half way along. The front face of the wall is extensively pitted by impacts from weapons of a variety of calibres revealing the half inch and one inch reinforcing rods, but the most spectacular damage is a 4m wide breach in the wall from which a spread of debris extends to a break of slope some 40m away.
The wall is fronted by a flat-bottomed anti-tank ditch, with an upcast bank on the NW or seaward(?) side. The ditch is some 3m across and about 0. 6m in depth and while the SW end is coterminous with the end of the wall, at the NE end the ditch extends for about 4m beyond the wall.
A trench running at right-angles to the SW end of the wall may have run up to an emplacement on the hillside to the ESE. A trench lying some 30m to the NW of the wall may have connected a network of trenches to the SSW and with a bunker to the NNE of the wall.
