Ordnance Survey First Series: Yorkshire 271

The personnel of the Ordnance Survey first undertook a full surveying of the country between 1842 and 1893, which resulted in the "First Series" maps. These were published as a series of large sheets for each county at a scale of six inches to the mile.

The Yorkshire 271 sheet (published 1854) was surveyed between 1848 and 1851, and covers the following area:

A fully zoomable version of the sheet is available to view on the National Library of Scotland's web site:

The subsequent 1890s revision of the six inch map was subdivided into four separate sheets: CCLXXI N.W., CCLXXI N.E., CCLXXI S.W. and CCLXXI S.E.
