Durham Maps
Ordnance Survey - First Edition
25 Inches to the Mile:
Around about 1860, Durham County, like the rest of the country, was surveyed to produce the First Edition
of the 25 Inches to the Mile Ordnance Survey Maps. There were to be fifty eight Sheets for the county, each
containing sixteen maps, though there were incomplete sheets around the periphery of the county.
This sample block of four sheets, covers
Sunderland,
together with an area to the West which approximates to the area covered by the Metropolitan City of Sunderland.
At the same time, Sunderland town centre was surveyed for a range of
120 Inches to the Mile Maps.
These show in splendid detail how the upper classes were housed. They had moved South, away from High Street, but even
they were not able to hide the location of their outside toilet.
The above maps will be downloaded in pdf format, so you can zoom, and pan round, to view them in as much details as required.
Should you wish to pan round the complete set of maps, then perhaps this Key Sheet for O.S. 1:528 Scale
Map Sections would be more appropriate.
Each map has been divided into 25 sections, numbered A1 to E5, in a 5 x 5 matrix. If you hold your cursor over the key sheet,
an appropriate section number will be displayed. Clicking on it will
display the selected section.
The controls for each section are contained within the rectangular border, placing your cursor within it will display the available controls.
You can pan, usually in eight directions, and the controls are suitably positioned within the border.
You can cross maps to allow you to view all 35 of them. When you reach the edge of a map on the periphery of the maps, the cursor will
indicate 'Edge of Maps'. There is overlap when panning around a map, but none when tranversing between them.
Should you find a location of interest, perhaps for which you have searched, such as a quaintly named alley, make a note of the Map Section Number
displayed above the map. To the right of centre, within the top border, you can select the parent map for this section, and display it on a
separate page. Using the Section Number you have noted, you can judge where the location is in the context of the whole map.
If you know the name of the place you are looking for, then this PlaceIndex
will take you straight to the map section where it is displayed.
Where the text is blue, you can click on it to display the map section. Where it is red, clicking on it will display an image of the place.
Finally, to the left of centre, again within the top border, you can select the option to go 'Back to Key Sheet'.
