The walls of Northern Ireland enrich the landscape with meaning. Many sides of buildings to separation barriers known as Peace Lines are home to murals conveying Republican and Loyalist messages.
Murals became popular in the 1960s. One of the first and most famous murals served as a border marker for IRA occupied "Free Derry" neighborhood of Londonderry. Others made their own murals to show neighborhood allegiance and to convey political messages.
There has been a recent change in Northern Ireland's murals. As the peace process continues some murals have been painted over with non-partisan unifying murals depicting works of literature or soccer players.
The murals of Northern Ireland prove once again that reading the landscape is an exactly way to understand cultures.
