Lunchtime Lecture by Dr Frank Cullen. Lunchtime Lecture series organised by the Royal Irish Academy Library and the Irish Historic Towns Atlas 'Mapping city, town and country since 1824: the Ordnance Survey in Ireland.' Cullen discusses the OS map of Dublin (1847) which casts a 'window on the city'. This map was made by military surveyors with civil assistants. They were empowered to enter and survey private property, this ensuring that the backs of buildings could be more accurately plotted on the map. Flower beds, sewers and water mains all feature on the map; the detail is astonishing. The methodology employed and the detailed processes of verification of drafts, revisiting sites and correcting the originals are discussed. The map was hugely popular, so many members of the public turned up at Mountjoy House, HQ of the Ordnance Survey, to make tracings that an order had to be made to stop them!
