Peace lines

Peace lines is a engineering topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Peace lines rather than just read about it. In short: The peace lines or peace walls are a series of separation barriers in Northern Ireland that separate predominantly Irish republican or nationalist Catholic neighbourhoods from predominantly British loyalist or unionist Protestant neighbourhoods. They have been built at urban interface areas in Belfast and elsewhere.

Key takeaways

  • Peace lines belongs to engineering; place it in that map before memorising details.
  • Learn the definition first, then one example that makes the definition concrete.
  • Connect Peace lines to a quantity you can measure, compute or draw — that is where exam questions come from.
  • Reproduce the core statement of Peace lines from memory before moving on to harder problems.

Reference excerpt

The peace lines or peace walls are a series of separation barriers in Northern Ireland that separate predominantly Irish republican or nationalist Catholic neighbourhoods from predominantly British loyalist or unionist Protestant neighbourhoods. They have been built at urban interface areas in Belfast and elsewhere. The majority of peace walls are located in Belfast, but they also exist in other regions of Northern Ireland with more than 32 kilometres (20 miles) in total.

History 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 effectiveness 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; 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 (yards) 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 become locations for tourism. Black taxis now take groups of tourists around Belfast's peace lines, trouble spots and famous murals. The most prominent peace lines in the past few years separate the nationalist Falls Road and unionist Shankill Road areas of West Belfast; the nationalist Short Strand from the unionist Cluan Place areas of East Belfast, the unionist Corcrain Road and the nationalist Obins Drive in Portadown and the unionist Fountain Estate and nationalist Bishop Street area of Derry. In 2008, a public discussion began about how and when the peace lines could be removed. Belfast City Council agreed to develop a strategy regarding the removal of peace walls on 1 September 2011. At the end of 2011, several local community initiatives resulted in the opening of a number of interface structures for a trial period. A study was released in 2012 indicating that 69% of residents believe that the peace walls are still necessary because of potential violence. In January 2012, the International Fund for Ireland launched a Peace Walls funding programme to support local communities who want to work towards beginning to remove the peace walls. In May 2013, the Northern Ireland Executive committed to the removal of all peace lines by mutual consent by 2023. In 2017, the Belfast Interface Project published a study entitled "Interface Barriers, Peacelines & Defensive Architecture" that identified 97 separate walls, barriers and interfaces in Belfast. A history of the development of these structures can be found at the Peacewall Archive. In September 2017, the Northern Ireland Department of Justice published its Interface Programme, established to deliver the commitment made by the Northern Ireland Executive to remove all Interface structures by 2023 under the Together: Building a United Community Strategy. By the end of 2023, more than 100 barriers still remained, but none had gone up since 2008. Surveyed in 2022, 83% stated they wanted the peace walls to come down. In September 2019, a series of events were held in Belfast to mark the anniversary of 50 years of peace lines in the city. This included an international conference alongside other events to discuss the past and possible future of the peace lines.

Worked examples

Example 1 — a first encounter with Peace lines

Start with the simplest possible case. Write down what Peace lines claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In engineering, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Peace lines before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Peace lines ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Peace lines

In research
Peace lines appears in engineering research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry
Engineering practice reuses Peace lines in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom
Peace lines is common in secondary-school and first-year university syllabi. It links to neighbouring topics 20th century in Belfast, 21st century in Belfast, Buildings and structures in Belfast, so understanding it makes those chapters shorter.
In everyday life
Look for Peace lines outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
