A new memorial has been unveiled to eight Orangemen from Derry who were murdered during the Troubles.
It remembers members of the institution, seven of whom were killed by the IRA and one by the UFF in the infamous Greysteel massacre.
Those honoured on the tablet are James McClelland and David Miller, killed in the 1972 IRA bombing of Claudy; George Hamilton, James Hood, Robert Stott, John Olphert and Cecil McKnight, who were all shot individually by the IRA, and John Burns, who was one of eight people killed by the UFF when they opened fire in the Rising Sun bar in Greysteel.
Relatives of the dead men joined with Orange grand master Edward Stevenson and City of Londonderry grand master James Hetherington for the formal dedication of the memorial tablet at St Columb's Cathedral.
A short service was conducted by the Rev Dean William Morton.
It has now been put on permanent display at the Apprentice Boys Memorial Hall in the city. Mr Stevenson said the murdered men will never be forgotten.
"I am delighted following the refurbishment of the memorial hall that it has now been allocated a permanent home in the lodge room of one of Londonderry's landmark buildings," he said.
"I pay tribute to the City of Londonderry Grand Orange Lodge for their endeavours in ensuring the sacrifice of eight of their members during the Troubles is never forgotten.
"The institution, as a whole, will always remember our murdered brethren and will always support their families, who continue to live with the painful legacy inflicted by terrorism."
Colin Campbell, a member of the Grand Orange Lodge of Ireland murdered brethren memorial committee, said: "The City of Londonderry Grand Orange Lodge felt it was important we had a permanent memorial to remember the eight brethren murdered locally.
"We are pleased we can now unveil a lasting memorial tablet in their memory."
He also placed on record the gratitude of the Institution to funeral directors Adair and Neely and D&R Hay, who jointly funded the memorial.
A memorial to eight men killed in a 1992 IRA bomb has been attacked. Flowers and wreaths laid at the memorial on the Drum Road close to Cookstown were scattered across the road in the early hours of yesterday morning. Passing cars drove over the floral tributes. The PSNI is investigating the incident which is believed to have taken place between 1.30am and 7.30am yesterday. The workers died on January 17, 1992 when a landmine exploded as their van passed by, returning from working at Lisanelly Army base in Omagh.
