A cross-border walk will form the centrepiece of events marking the first anniversary of the death of Martin McGuinness.
"The Chieftain's Walk", from Derry’s Glenowen area to Grianán fort in Co Donegal, is one of several commemorative events planned over the next week.
A Mass will be celebrated at St Columba’s Church, Long Tower at 7.30pm tomorrow, the first anniversary of Mr McGuinness's death.
His Requiem Mass also took place at the church close to the city's walls.

An underage GAA blitz tournament will be held at Celtic Park on Saturday, while Ógra Shinn Féin will also stage its national youth congress in Derry on the same day.
Many members are expected to remain in the city to take part in the walk to Grianán the following day.
On Monday, former Sinn Féin president Gerry Adams will also host a talk “Remembering the Chieftain” at Derry’s Millennium Forum.
He is expected to give some personal memories of his long association with Mr McGuinness.
Mr McGuinness’s family has organised the commemorative walk because it follows a route which the late deputy first minister enjoyed walking himself.
It will also raise money for the North West Cancer Centre at Altnagelvin Hospital in Derry.
Launching the walk, Mr McGuinness’s son Fiachra said the ancient Grianán ring fort close to the Derry border was a “very special place” for his father.
“He loved to walk up to the fort so when we were considering an event to hold in his memory, a walk from Glenowen to Grianán was the obvious thing to do,” he said.
A book offering different perspectives on Mr McGuinness's life will be launched next Wednesday.
Martin McGuinness, The Man I Knew, by Jude Collins, features contributions from Baroness Eileen Paisley, Senator George Mitchell and former Ulster Unionist minister Michael McGimpsey among others.
It will be launched at Eason’s bookshop in Derry.
