This example of a 'Welsh Not' was found at Garth School, Bangor, which has since been demolished. The 'Welsh Not' was used in some schools during the eighteenth and nineteenth century in a bid to prevent pupils from speaking Welsh. The 'Welsh Not', which usually consisted of a small piece of wood or slate inscribed with the letters 'W.N', was hung around the neck of a child who was caught speaking Welsh. At the end of the school day, the child wearing the 'Welsh Not' would be punished by the schoolteacher.
