Despite only being approximately 6 miles at its widest point, Belfast has almost 20 miles of peace lines, walls and other structures that divide its two largest communities.
The first such structure was built 45 years ago, shortly after the beginning of a conflict that has killed over 3500 people and injured in excess of 50,000 men, woman and children.
So why, despite a peace process that was agreed almost 20 years ago, do these structures still exist throughout Northern Ireland's capital city.
For the past two years, John Irvine has been photographing these interface areas and their surrounding geography. The purpose of this photographic journey was not just to educate, but to provoke thought and conversation in others that weren't aware of their existence.
