A new Trinity College website bringing a unique 17th-century map collection together for the first time in 300 years as a public online resource, is now online.
The Down Survey of Ireland, undertaken by the Cromwellian regime in the years 1656-1658, was the first ever detailed land survey on a national scale anywhere in the world and measured all the estates to be forfeited by the Catholic Irish.
Led by Dr Micheál Ó Siochrú, associate professor in Modern History at TCD, historians have tracked down over 2,000 of the surviving survey maps in dozens of libraries and archives throughout Ireland, Britain and France, and brought them together as a free online resource.
By overlaying all the surviving maps onto Ordnance Survey maps, Google maps and satellite imagery and employing GIS technology, this new resource transforms our understanding of landownership, settlement and religious changes during a very turbulent period of Irish history.
Features of the online resource include the first representation of the mid 17th century road network in Ireland, new maps illustrating the dramatic change of land from Catholic to Protestant ownership, visual representations of the locations of violent assaults and murders during the 1641 rebellion and a database of 10,000 major land owners in Ireland.
