The graffiti, which depicts a face accompanied by the words ‘Bunker Bizzness’ and the German phrase ‘Der Soldat Ohne Namen’ – ‘The Soldier Without Name’ in English, was found inside a bunker near the car park at Noirmont.
Paul Burnal of the Channel Islands Occupation Society said that the culprit was clearly artistically talented but defacing historical buildings was unacceptable.
He said: ‘A graffiti artist has been busy at work inside one of the bunkers that’s permanently open.
‘The face that they have drawn has a lot of detail, so they must have taken a long time to do it, and they would have been doing it in the dark as there is no lighting in there.
‘It’s a shame because whoever did it is very artistically talented but this is not the right place to do it.
‘They have done it on a historical building – this is going to cost money for us to clean off now.’
Mr Burnal said that the vandalism may mean public access to the fortifications will have to be restricted.
He said: ‘We are now going to have to put security gates up around bunkers that were opened up and we are going to have to work out how we clean off the graffiti.
He added that there was little that could be done about graffiti artists defacing historical buildings and a similar trend was taking place in France.
He said: ‘Historical structures seem to be getting targeted by these graffiti artists.
‘It’s happening a lot in France as well – the German fortifications are getting covered in graffiti. They call it ‘tagging’ there.’
Mr Burnal added that similar graffiti had been drawn and then cleaned off German fortifications at St Ouen’s Bay around Christmas time.
