The OS was established in 1791 to prepare maps of southeast England as part of the defences against the French. Although the war ended in 1814 the OS has continued since then to map the entire country.
Huntingdonshire was surveyed for the Old Series OS in 1808-1821: we have a book containing reprints of published Old Series one-inch maps for this area, and photostats of the surveyors' draft maps on a scale of 2 inches to the mile. Huntingdonshire was then surveyed for the County Series (or New Series) in 1884-87, 1899-1901, and (some places only) 1924-25. Huntingdonshire Archives holds a large collection of County Series maps on the popular 25-inch (1:2500) and 6-inch (1:10560) scales. We also have some 6-inch maps from the post-war provisional edition. There are some gaps in our holdings: Huntingdon Library has some maps which can fill the gaps, however.
The county was first surveyed for the National Grid in 1961. We have some NG maps on various scales, though coverage is patchy.
