The Peace Walls were built primarily to separate neighbourhoods with predominantly Catholic and Protestant populations. The purpose was to prevent violence between the two communities, as sectarian clashes and riots had become increasingly frequent during the Troubles. The walls were constructed by the British Army as a temporary measure to quell the violence, but they eventually became permanent fixtures of the Belfast cityscape.
The walls have been criticised by some for perpetuating division and hindering reconciliation between the Catholic and Protestant communities. However, they have also been praised by others for preventing further violence and saving lives. The continued presence of the walls remains a contentious issue in Northern Ireland today, and their eventual removal is often discussed in the context of promoting peace and reconciliation.
