The capital of Northern Ireland, with 330,000 inhabitants, is the second largest city on the Irish island after Dublin. However, more than half of the six million Irish people live in the corridor between Belfast and Dublin. In the 1970s the inner city districts were again and again the scene of the Northern Ireland conflict. The Peace Line, a wall in West Belfast (west of the expressway “West Link”) dates from this time. It separates the areas of Falls Road, where the Catholic Republicans lived, from Shankill Road, the stronghold of Protestant unionists. On both sides the wall is painted with propagandistic murals.
