Down Survey of Ireland.

Jimmy Laffey

The 17th century ‘Down Survey’ resulted in the first systematic mapping of Ireland, with unprecedented levels of organisation and accuracy. It proved a milestone in Irish and world cartography and its maps
were used as a record of land tenure almost until the advent of the Irish Ordnance Survey in the 1820s.
