Old Ordnance Survey Maps for Caernarvonshire


  • These are our maps for Caernarvonshire:

    All maps are available from our On-line Mapshop or from selected bookshops in the area.

    The following maps are taken from the OS 25" maps and reduced to a scale of approximately 15 inches to the mile. They are extremely detailed, showing individual houses, details such as railway tracks, pathways, pubs, factories and even minutiae such as fountains and signal posts. Obviously they cover quite a small area, normally a mile by a mile and a half each. For further details click on the links below.
