The alabaster effigy of William Bulkeley c.1490, in St Mary's and Nicholas's Church, Beaumaris, Anglesey, North Wales. The effigy is covered in graffiti, Something that started after the Reformation.
The newer graffiti overlays the old, with initials and names merging into each other.
What looks like a descendent Richard Bulkeley has carved his name onto the effigy in 1601.
A study of the door to St Saviours near Ribchester, showing an unusual mark in the centre of the photo, not dissimilar to a stone mason's mark.
A curled circular mark found on the corner of a fireplace in the White Lion Hotel in Hebden Bridge, West Yorkshire. Probably 17th century.
Two cut out circular marks found in the same fireplace of the White Lion Hotel. The stone may have been re-used from elsewhere.
Four horse shoes found in a sandstone block in a wall in Wavertree in Liverpool.
Possible stone mason's mark in an archway in a church in Anglesey.
More modern graffiti found on the sandstone of the Sankey Viaduct, near Earlestown, in the north-west of England, built by George Stephenson between 1828-1830. It was the first railway over the first canal.
When looking at graffiti like this, you often wonder who the person was. Maybe 'K J' is still with us....
