Cassini’s map of the week – Guildford


Guildford 1816 Ordnance Survey Old Series

Ever wondered why Guildford developed in the location seen today? By referring to the Cassini Old Series maps it can be seen how Guildford, the county town of Surrey, developed in a gap in the North Downs, through which the River Wey passes. Any traveller in Surrey heading from North to South, or vice versa, would make straight for the gap in the chalk hills rather than climbing the the escarpments of the downs.

Before the advent of contour lines each hand drawn Ordnance Survey map indicated the relief of the land with hatchuring (from the Old French word hacher, to cross hatch) making it clearly visible how the landscape played a vital role in the positioning and settlement of cities, towns and villages across the length and breadth Britain.
