The co-ordinate system used for this map is WGS84 (World Geodetic System 1984) / ETRF89 (European Terrestrial Reference Frame 1989). This system is used as a reference for GPS and online maps of Ireland.
These co-ordinates can be converted to the Irish Grid Reference System (IG) and the Irish Transverse Mercator (ITM) coordinate reference system. The Ordnance Survey Ireland (OSI) are currently migrating from IG to ITM. Click here for further information.
Co-ordinate converters are available from the following websites:
The About Tab:
Provides some advice on using the map. This tab displays by default on the map page of the website and the full screen Barracks Map Viewer.
The Legend Tab:
Click the ‘Legend’ tab (as above) to view the map legend. This is useful if you are viewing multiple layers at the same time.

Click the menu button to show or hide the information panel.
Each map marker represents the known or approximate location of an eighteenth-century barracks on the island of Ireland. The markers change from layer to layer (per slideshow above).
Please note that the co-ordinates used are based on preliminary research and it is the ultimate aim of this project to provide accurate co-ordinates for every eighteenth-century barracks. Please get in touch if you have information to make the map more accurate.
Zoom Controls & Home Button:
Use the + icon to zoom in and the – icon to zoom out. Click the house icon to return to the original map extent.
Use the map’s integrated search bar to find an address or place.
Changing the basemap:
The default basemap for this map is ‘OpenStreetMap’. To change the basemap to satellite imagery, click the Basemap Toggle Button in the top right of the map screen.
A pop-up window will appear if you click on a map marker. Each map layer contains different information. For example, the ‘All Barracks’ layer contains information such as: alternate names for the barracks; the latitude and longitude of the map marker; how close we think that pin is to the actual barracks site (proximity); a link to further information if available on this website (e.g. full articles available for barracks in Armagh); a link to the relevant placename record for the location on logainm.ie; and a link to the relevant entry for the barracks in the National Inventory of Architectural Heritage (NIAH) if available.
If you have selected a number of layers you can navigate through the pop-up windows for a particular location. The number of pop-ups active for the location will appear in the grey box at the top left of the pop-up window (per image below) and you can click the arrow button (highlighted below) to navigate through the pop-ups for each layer.
You can share content from the map via Facebook, Twitter, Google Plus or Email by clicking the ‘Share’ icon (above) which is located at the top right of the map screen. Code to embed the map in another website is also provided. When you click the ‘Share’ icon, a ‘Share’ dialogue box appears (pictured below). If you wish to share the current map view (i.e. if you have zoomed in on a particular location and wish to share that view), ensure the ‘Share current map extent’ box is checked.
