A couple of weeks ago I was cycling along the coastline of Normandy and saw a number of newly commissioned memorials. I came away strangely unaffected by any of the sculptures I saw. For me there was not enough mental space left for the viewer to make his or her own interpretations, space that is essential for conjuring thoughts and emotions. Then I saw the remains of the Mulberry harbour at Arromanches. It’s like some great disjointed serpent, its tail snaking back to England. It’s a powerful monument in itself with great sculptural qualities. This one remnant of the battle seemed sufficient to trigger a range of emotions and responses. I’m not sure we need any more commissioned pieces for tourists to scramble over and pose for selfies.
