Pembrokeshire - Old Ordnance Survey maps, 1:10560 scale (6inch to the mile)

The maps are highly detailed, showing individual buildings, roads, railways, footpaths, boundaries, and features such as rivers, woods, and hills. They also include information on land use, such as agricultural land, woodland, and urban areas. The maps are printed in black and white, later maps had contour lines in red or blue. The maps are typically divided into sheets, with each sheet covering a specific area of the county. The sheets are numbered and can be assembled into a larger map of the county. Each sheet includes a key to the symbols used on the map, as well as a scale bar to help users estimate distances.
