Manchester is preparing to mark a year since the terror attack at the city's Arena, which killed 22 people.
Here is the programme of events planned for the city:
Volunteers will hand out message tags which can be hung on branches along the trail.
It will give people the chance to leave tributes to the victims, or share messages of support and solidarity.
A memorial service will take place at Manchester Cathedral - attended by an invited congregation including the families of those who lost their lives, those injured, first responders, civic leaders and senior national figures.
The service will be streamed live in Cathedral Gardens - and at York Minster, Liverpool Metropolitan Cathedral and Glasgow Cathedral.
A national minute of silence will be held around the country to mark the first anniversary of the bombing.
Albert Square will open to the public at 6pm, so people can gather in place ready for the commemoration events.
Albert Square, the scene of remembrance on the day after the attack, will host a public event in the early evening giving people the chance to come together again and stand in solidarity.
The event is open to anyone, and features a mass-singalong "in a united act of remembrance".
The event will be supported by choirs from across the region, and will include a selection of songs that evoke pride and solidarity.
As dusk falls, song lyrics will be projected onto the pavements and buildings of St Ann's Square - another area which became an important public space after the attack in May last year.
It will be a space for reflection and to pay respects to those who died.
The projections will run for five nights after the anniversary, and people can submit song lyricswhich will help reflect the event or which could inspire hope or pride in others.
At 22:31, exactly one year on from the moment a suicide bomber detonated an explosive at Manchester Arena, bells will ring out in churches across the city.
It's an act of commemoration for the 22 people who died, and the countless others whose lives were changed forever by the attack.
