More than 50 barriers still demarcate territory
There are 53 remaining peace walls in Northern Ireland.
These are the structures which fall under the responsibility of the Department of Justice; there are also around another 20 owned by the Housing Executive.
There are even some on privately-owned land which have been forgotten about.
The vast majority of them are in Belfast.
There are 18 peace walls or gates in west Belfast including the biggest, which runs between the Falls and Shankill roads, and the oldest, which is located at Cupar Way and dates back to 1969 and the outbreak of the Troubles.
There are also 18 in north Belfast including several at Duncairn Gardens, Woodvale and one of the tallest barriers, a six metre metal fence at Alliance Avenue.
In east Belfast, there are four barriers.
Three of these separate the lower Newtownards Road from the Short Strand area while the fourth is at Mountpottinger Road. South Belfast is the only area of the city where there are no peace walls.
Outside of the capital city, Londonderry has the most peace walls including one at the historic Bishop Street flashpoint.
There are five in Portadown, all of which were erected since 1998 and particularly in reaction to the Drumcree dispute.
They include Charles Street, Obins Street and Northway, while there is one in Lurgan located at Margretta Park.
