Thousands of white balloons released over Dublin to mark 25 years since Berlin Wall came down
More than 1,400 young people from all over the world took part.
The balloon release was part of the One Young World summit that has been taking place in Dublin over the past three days.
The event, which concludes today, saw attendees from 190 different countries present and discuss a broad range of topics on major issues facing the world.
The theme for this year's summit is 'Peace and Conflict Resolution'
Twenty-five sets of balloons were made to represent the number of years since the fall of the historic wall.
Delegates were given a balloon and lined up along the River Liffey this afternoon to recreate the famous wall.
At 2pm they released the balloons, creating a spectacular scene over the Dublin skyline.
The Berlin Wall was a barrier constructed by the German Democratic Republic in August 1961 as a means to cut off West Berlin from surrounding East Germany and East Berlin.
It was kept up for 28 years and was taken down in November 1989.
