Ordnance Survey 6 Inch Maps, 1842

The Ordnance Survey was established in Britain in 1791; in 1824 the Survey established its Irish headquarters in Dublin.
The Ordnance Survey took its name from the Board of Ordnance, a military organisation, and the field surveys were carried out by men of the Royal Engineers who were based in various barracks around the country. They had to determine the boundaries of over 60,000 townlands and standardise the names of each of them.
The maps were drawn on a scale of 6 inches to one mile and published between 1833 and 1846. The 1842 Ordnance Survey 6 Inch Maps for Galway are now available here.

John O’Donovan and Eugene Curry assisted in the authentication of local placenames. The results of these investigations are contained in the OS Place Name Books. These record townland names along with Irish names and their translation. A Database of Galway Place Names is available online. It is also available in Library Headquarters on microfilm.
