Historic Environment map viewer
This online map of Northern Ireland allows the user to search, browse, or navigate to a particular area to explore local heritage.
Before you start
Datasets on the map viewer include sites and monuments, historic buildings, industrial heritage, historic parks and gardens, battle sites, defence structures, archaeological investigations, and shipwreck sites.
By clicking on a specific site, you can view a ‘pop-up’ which provides a brief description. Users can also access historical six-inch Ordnance Survey map editions, contemporary OSNI maps and orthophotography (aerial photography).
The Sites and Monuments GIS layer and associated database are currently undergoing maintenance, which is causing delays in updating them with new information. HED are aware that in a small number of cases locational information may need to be corrected, but if you have any queries about an individual site, please contact Historic Environment Record of Northern Ireland (HERoNI). For Scheduled Monuments, the Scheduled Zones layer is an indicative dataset, and you should request copies of the official scheduling declarations held by HERoNI if you are considering any new work that might affect these sites.
