The Interfaces Map has been redrawn for the 2017 Interface Barriers, Peacelines and Defensive Architecture research, carried out for BIP by the Institute for Conflict Research (ICR). The map now covers Derry/Londonderry, Portadown and Lurgan as well as Belfast.
You can use the menu above the map to filter barriers by their cluster group, form (type), ownership and decade built. Click here to view in full screen.
The interactive map above was created by the Detail Data project (a partnership between NICVA and TheDetail.tv funded by the Big Lottery), based on the research carried out by Neil Jarman at ICR.
The data, which includes the barrier lines in GIS format, is publicly available and is published under the Creative Commons Attribution ShareAlike (CC BY-SA 4.0) licence. You can download it from the Detail Data Portal.
