Flak towers and personnel shelters at railway gun firing position
Wn123 Mulheim site overview
What to see
A few hundred metres south west of the Wn87 Unstrut railway gun site between Coquelles and Sangatte you can find another of the many positions along the route where railway guns operated around the Calais, Cap Gris Nez, and Boulogne-sur-Mer area.
This site featured a large turntable which allowed the two 28cm K5 guns under the command of the E725 army unit to be angled in the direction of their targets over the Channel in England.
While the turntable is no longer in place and the area used for agriculture, you can see some of the supporting buildings which surrounded the position.
The most prominent is a special construction flak tower for a 2cm anti-aircraft gun – one of two originally at Wn123, along with four Wellblech personnel shelters and an open emplacement for a 5cm KwK anti-tank gun.
Three of the Wellblech shelters and the KwK emplacement can still be seen from the public footpath which runs along the site where the railway line used to be located.
