Parades are a prominent festure of North Ireland society,more so than in the rest of Ireland or in Britain. Most are held by Protestant fraternities such as the Orange Order, and Ulster loyalist marching bands. Each summer,during the "marching season",these group have hundreds of parades,deck streets with British flags,bunting and specially-made arch,and light large towering bonfires. The biggest parades are held on 12 july(the twelfth). There is often tension when these activities take place near Cathlic neighbourhoods,which sometime leads to violence.
