Graffiti where?

For the House-Bunker -  internal house within it - this is the original image from a Guernsey bunker that inspired much of the idea some years ago. However, I need further images of the writing and cannot remember where in Guernsey this particular fortification was.

Gloucester church graffiti, but no ships to keep St. Nicholas, Salthouse company.

Sudanese temple graffiti.

 Trying out these 2 images mounted under acrylic.  I'm attracted by the idea of a protective covering or shield over these carvings at long last, a small recompense for their centuries of exposure to the elements and marauding colonialists wanting to leave their mark.
