Sword Beach bunker site codenamed ‘Trout’ by D-Day planners

Wn21 Lion sur Mer site overview

What to see
One small shelter is all that remains today of the Wn21 site, codenamed ‘Trout’ by the Allied planners of D-Day.
It was one of several sites given fish codenames in this Sword Beach sector, which also included Wn14 ‘Sole’, Wn18 ‘Skate’, and Stp20 ‘Cod’. Further inland, the larger sites and batteries were named after British car makers including Hillman, Morris, and Daimler.
Located on the edge of the camping site around 200m from the beachfront, this small shelter – possibly an ammunition store - is a tiny reflection on a site which once boasted observation posts, 1694-type Ringstands for 5cm KwK anti-tank guns, Tobruks, anti-aircraft gun positions, field shelters, and an open emplacement for a 7.5cm antitank gun.
The bunkers and positions were all linked by a series of trenches – all of which are now buried under modern housing.
Some of the original houses on the beachfront and low cliff area were fortified with lower levels of concrete builds camouflaged as residential buildings.
This area took a hammering from Allied naval ships in the Channel prior to the D-Day landings by British forces on the beach here.
