Several clubs also have Christian messages publicly displayed at their grounds. Between 1995 and 2010, Northern Irish club Glentoran F.C. had a sign with "Jesus" on it at The Oval before it was removed due to Glentoran needing the space for advertising. Fellow Northern Irish club Portadown F.C. had a sign with "Life without Jesus makes no sense" along the side of Shamrock Park. Football clubs have also used their grounds for Christian services including Rangers using Ibrox Stadium for memorial services for the 1971 Ibrox disaster and likewise Liverpool F.C. using Anfield for annual memorial services for victims of the Hillsborough disaster.
