The peace lines or peace walls are a series of separation barriers in Northern Ireland that separate predominantly republican and nationalist Catholic neighbourhoods from predominantly loyalist and unionist Protestant neighbourhoods. They have been built at urban interface areas in Belfast, Derry, Portadown and elsewhere.

The majority of peace walls are located in Belfast, but they also exist in Derry, Portadown and Lurgan, with more than 20 miles of walls in Northern Ireland.

Although temporary peace walls were built in Belfast in the 1920s (in Ballymacarett) and 1930s (in Sailortown), the first peace lines of "the Troubles" era were built in 1969, following the outbreak of civil unrest and the 1969 Northern Ireland riots. They were initially built as temporary structures, but due to their effective nature they have become wider, longer, more numerous and more permanent. Originally few in number, they have multiplied over the years, from 18 in the early 1990s to at least 59 as of late 2017;[3] in total they stretch over 34 kilometres (21 miles), with most located in Belfast. They have been increased in both height and number since the Good Friday Agreement of 1998. Three-quarters of Belfast's estimated 97 peace lines and related structures (such as gates and closed roads) are in the north and west of the city. These are also the poorer and more disadvantaged areas of Belfast. 67% of deaths during the sectarian violence occurred within 500 metres (550 yd) of one of these "interface structures".

The stated purpose of the peace lines is to minimise inter-communal violence between Catholics (most of whom are nationalists who self-identify as Irish) and Protestants (most of whom are unionists who self-identify as British).

The peace lines range in length from a few hundred metres to over 5 kilometres (3 mi). They may be made of iron, brick, steel or a combination of the three and are up to 8 metres (25 feet) high. Some have gates in them (sometimes staffed by police) that allow passage during daylight but are closed at night.

In recent years, they have even become locations for tourism. Black taxis now take groups of tourists around Belfast's peace lines, trouble spots and famous murals. (Source: Wikipedia)
