| 説明 | A nice example of a small twin-loophole pillbox on the River Wye. It is one of a pair, the second being across the river facing this one. They appear to protect what may have been an important railway crossing.The pillbox is made from reinforced cast-concrete to the bullet-proof standard. There are only two loopholes, side by side, and facing south along the railway bridge. There is standing room only, but a generous firing shelf has been provided below the loopholes. This is a solid shelf to ground level, increasing the thickness of the lower front face of the pillbox to around 4 feet; and could be considered shell-proof. After the initial frenzy of pillbox construction in 1940/1941 the decison was made to abandon the pillbox as a forom of permenant stop-line fortification and to adopt the more adaptable (and cheaper) field fortification. Pillboxes were to be authorised in special circumstances, but would be supported by a network of field defences. By 1941 it was also acknowledged that the original bullet-proof standard of pillbox would perform poorly against the heavier German weapons, and that specification was to be diminished. This pillbox, not built to a recognised standard, is likely to have been build |
