Ordnance Survey Ireland maps

Maps are a family historian’s friend. They help us picture where our ancestors lived, the neighboring towns and parish churches, and the geographic features of the area.

Ordnance Survey Ireland (OSi) was established in 1824 to carry out a survey of the entire country on behalf of the English government, which  was interested in updating land valuations for taxation purposes and assessing natural and man-made resources in Ireland. The resultant maps were amazingly accurate. Read about the creation of OSi historic maps here.

Today you can view all of the detailed OSi maps online, for free. Start at the GeoHive website.

The maps are scaled at 1:50,000, or about .8 mile per inch. Originally priced at $16, the maps are now selling online for $12. We reduced the price to $8 at the recent Celtic Connections Conference.

As a blog-reader, you too can get them for only $8 by contacting me directly (blog@irishgenealogical.org).

To determine what maps remain in stock and what each map covers, look at the IGSI bookstore. Find the maps by putting Discovery as the title.

[The OSi online shop has nifty big-picture maps showing what’s covered by the Discovery Series (for the Republic) and what they now call the Discoverer Series (for Northern Ireland).]

HMAP02IGSI also has a limited number of out-of-print maps scaled at 1:126,720, or about one-half inch to a mile, which we’ll sell for $3 each. The maps were published in 1988 – but hey, towns and rivers don’t move to new locations. You can see these maps in the bookstore by putting half inch as the title.

Again, to get lower-than-online prices for Discovery Series and/or Half Inch maps, let me know what you’d like to order and I’ll email you an invoice.
