Between 1837 and 1846 Ordnance Survey Ireland completed the first ever large-scale survey of an entire country. Acclaimed for their accuracy, these maps are regarded by cartographers as amongst the finest ever produced.
As the national mapping archive service for Ireland, OSi has captured this and later mapping data in a digitised format.
National Map Services supply the following Historical Maps:
A4 & A3, Black & White and Colour 6”
A4 & A3 Black & White 24”
