The Down Survey
Following the Cromwellian Conquest of Ireland at the beginning of the 1650s, the Commonwealth government was indebted to many private individuals – adventurers – who had advanced sums of money to finance the war in Ireland. In addition to this, many soldiers who fought in the war were owed large arrears of pay. Both classes were to be repayed by the granting of confiscated lands in Ireland. To facilitate this extensive transfer of land, William Petty was appointed, in 1654, to measure and map, within 13 months, the forfeited lands, the crown lands, and the church lands in the 22 counties set apart for the soldiers.

About the Down Survey Maps
The maps record townland names, acreages, territorial boundaries and quality of land: pasture, mountain, arable, bog etc. Features such as rivers and mountains are noted, as are castles, churches and important houses. The scale used was generally 40 perches to an inch, one perch equalling 21 feet (6.4 metres). The Down Survey also preserves many 17th century placenames. More info >>

Petty’s ‘Hiberniae Delineatio’ County Map
Sir William Petty used the Down Survey as the basis of his atlas of Ireland, ‘Hiberniae Delineatio’, commonly called Petty’s Atlas. It was the first printed atlas of Ireland, and contained a map of Ireland, maps of the provinces, and maps of the counties of Ireland. The atlas was engraved sometime about 1663 but not published until c. 1685. The county maps were drawn at a scale of two Irish miles to an inch and show the barony boundaries. The Clare map is given here, preserving some of the lost information from the destroyed parish and barony maps.

William Petty
William Petty (1623-1687) was an English economist, scientist and philosopher. At the time he was appointed to map the forfeited lands, he was employed as physician general to the Commonwealth forces in Ireland. Petty gained fame, and considerable personal wealth - including 30,000 acres near Kenmare, Co. Kerry, as payment for completing the Down Survey. He left for England after the survey and was knighted by Charles II, but returned to Ireland in 1666 where he remained until shortly before his death, in 1687.
