Free Derry Corner has had a tribute to murdered journalist Lyra McKee added to its iconic mural.
The famous civil rights-era slogan on a gable wall is regularly altered to reflect community sentiment in the Bogside estate.
The city's Catholic bishop has said the nationalist community needs to be liberated from dissident republicans blamed for Ms McKee's shooting.
The white gable wall with “You are now entering Free Derry” painted on it in black has had many additions over the years for various causes, such as turning pink to support organ donation appeals.
This Easter Sunday, it now bears the hashtag #NotInOurName and the words RIP Lyra alongside a simple heart.
Ms McKee died on Thursday night, after being shot during rioting in the Creggan.
It is thought a gunman aiming to kill police hit the 29-year-old as he fired indiscriminately during disturbances.
Many heartfelt tributes have been paid to Ms McKee, who’s death has widely been condemned as a senseless act of barbaric violence which has devastated her family, partner and those closest to her.
Police have said they believe the response to the young woman’s killing has marked a sea change in the local community.
Two men, aged 18 and 19, arrested over the murder of the journalist have been released without charge, the Police Service of Northern Ireland said.
Detective Superintendent Jason Murphy said: "We have received very positive support from the community but we need to convert this support into tangible evidence that will enable us to bring Lyra's killers to justice.
"I know there will be some people who know what happened but are scared to come forward but if you have information, no matter how small, please contact detectives."
Police believe Ms Mckee's murder was carried out by violent dissident republican group, the New IRA.
Det Supt Murphy fears a new breed of terrorist is coming through the ranks in Northern Ireland.
The New IRA is an amalgam of armed groups opposed to the peace process and it recently claimed responsibility for parcel bombs sent to London and Glasgow in March.
Officers are urging anyone who can help bring those responsible to justice to come forward, vowing to handle the situation sensitively in recognition of the fear that still exists in areas where paramilitaries try to exert control.
Police believe the violence in which Ms McKee was killed was orchestrated in response to an earlier search by officers aimed at averting imminent trouble associated with this week's anniversary of the Easter Rising.
Around 50 petrol bombs were thrown in the confrontation and two cars were burned out.
Meanwhile, Sinn Féin President Mary Lou McDonald has said dissident republicans behind the murder should cease their activities.
Speaking at an Easter Commemoration at Milltown Cemetery in Belfast, Ms McDonald said that there is “no support for armed actions”.
“We saw on the streets of Derry the brutal killing of Lyra McKee,” Ms McDonald said.
“We extend our sympathy and solidarity to her family, to Sara, and to all who loved her.”
She added: “There is no cause progressed by armed actions. There is no justification for armed actions. There is no support for armed actions.
“This Easter, the people of Derry and beyond have said that with one voice.
“The war is over.”
