 Portadown is located in an area known during the troubles as the "murder triangle" because of the high number of killings carried out by paramilitary organisations.The town is the site of an annual parade in July by an ex-serviceman's lodge of the Orange Order, from St Mark's Church in the town centre, where participants lay wreaths at the war memorial.Participants then marched to Drumcree Church through the predominantly nationalist Obins Street (also known as the "Tunnel" area because of an underground walkway connecting it to a higher level at the bottom of Fowler's Entry/Mary Street/John Street).
