From a nucleus of 20,000 maps acquired with the RDS Library and the Joly Library in 1877, the National Library's collection of maps has grown to approximately 150,000 items. The collection is predominantly Irish but there are maps which relate to Britain, Europe and the world at large.

Details of maps from the twelfth century to the early nineteenth century, including military and engineering maps, estate maps and grand jury county maps can be found in the Manuscript Maps section of the website.

The Library's  very extensive collection of Ordnance Survey maps date from the first government commissioned survey of the whole of Ireland in the early nineteenth century, to the present day. There are also a large number of general printed maps many of them in atlases and tour books.

See the Accessing Maps section to find out how to consult maps.
