Young people in Nottingham have raised £60,000 to open a park in memory of their friend who was murdered four years ago.
Seventeen-year-old Jason Spencer was stabbed to death by Reuben Valentine when a play fight got out of hand.
The new park, on Valley Road, Sherwood, was created so youngsters can get together safely and commemorate Jason.
Angela Spencer, Jason's mother, will open the site on 3 June - her son's birthday.
It has facilities including a multi-play area and an outdoor gym, while a skatepark is due to open later in the summer.
Councillor David Trimble, portfolio holder for leisure, culture and tourism at Nottingham City Council, said: "Young people have been passionate and hard working in coming up with ideas for this project and raising a large amount of the money needed themselves.
"I am pleased we have all been able to work together to turn these ideas into a reality and commemorate the memory of Jason.
"I hope young people and the local community will benefit from the new facilities and the skatepark to come."
The charity Youth Bank and the city council also contributed funding for the project.
Valentine was jailed for life in 2007 for Jason's murder.
