The history of Northern Ireland is painted on its walls. “People have painted murals in Northern Ireland for almost a century. For most of that time, they were almost entirely unionist. Every year on 12 July, unionists decorated their streets to celebrate the victory of the Protestant William III over the Catholic James II in 1690. When new trolley and electricity lines interrupted this annual custom, unionists began to paint “King Billy” on their gable walls instead. For the next 60 years, these portraits were repainted every summer. Then came the Troubles, which inspired republican murals, and dramatically transformed loyalist murals, too.” – New Statesman
