1842 Ordnance Survey 6-Inch Maps of County Clare





The Ordnance Survey

The Ordnance Survey (OS) was originally established in Britain in 1791, and in 1824 the Survey established its Irish headquarters in Dublin, in order to undertake the mapping and measurement of Irish townlands. The maps were drawn on a scale of 6 inches to one mile and published between 1833 and 1846. They were later revised on a county-by-county basis. More info >>
