Local schoolchildren released dozens of white balloons bearing messages of goodwill to mark the International Day of Peace.
They were joined by Hammersmith & Fulham Mayor Cllr Mercy Umeh in Lyric Square, Hammersmith, as well as Youth Mayor Aminata Koroma.
“It was an important reminder of how lucky we are to live without war,” said Cllr Umeh, who organised the event.
“As well as a chance to think of others whose lives are torn apart by conflict or who are struggling to find peace for other reasons.”
Cllr Sue Fennimore, H&F Cabinet Member for Social Inclusion; religious leaders from a range of faiths; and chief superintendent Gideon Springer, Met Police borough commander, all made speeches and invited the crowd to reflect.
The crowd lit candles in a shared hope for a more peaceful future for both strangers and those closer to home, as well as messages for a giant model dove, which was raised up in the square.
The event was organised by H&F Council and HammersmithLondon business improvement district on Wednesday 21 September. It was one of many across the world to mark the International Day of Peace, established by the UN in 1981 to strengthen and promote peace among all nations.
