Berlin Wall: Thousands of balloons released to mark fall

(BBC) - Some 8,000 helium balloons have been released into the night sky over Germany's capital at the culmination of events to mark the 25th anniversary of the fall of the Berlin Wall.

Earlier, Chancellor Angela Merkel said the fall of the wall had shown the world that dreams could come true.

Tens of thousands of people attended events, including a "citizen's party" at the Brandenburg Gate.

The Berlin Wall was built in 1961 to stop people fleeing the communist East.

Its fall in 1989 became a powerful symbol of the end of the Cold War.

The white balloons - perched on 3.6m poles to match the height of the wall and stretching for 15km (nine miles) - were released one by one to symbolise the breaching of the wall by crowds of protesters.

The Berlin State Orchestra under Daniel Barenboim played Beethoven's Ninth Symphony "Ode to Joy" in front of the Brandenburg Gate.

"We're the happiest people in the world and we're thrilled that you brought the Berlin Wall down 25 years ago," said the Mayor of Berlin, Klaus Wowereit, as the first balloons were sent aloft.

"Nothing and no-one can stand in the way of freedom."

The release came amid a massive open-air party at the Brandenburg Gate. Earlier at the party, UK performer Peter Gabriel sang a version of David Bowie's Heroes.

The day's events began with a brass band playing, evoking the trumpets which brought down the walls of the biblical city of Jericho.

Chancellor Merkel, who grew up in East Germany, and other officials laid roses in one of the remaining sections of the wall.

Speaking at the opening of a new information centre about the Wall, Ms Merkel said it was easy to forget what had happened and it was important to remember it.

"We can change things for the better," she said. "This is the message for... Ukraine, Iraq and other places where human rights are threatened.

"The fall of the Wall showed us that dreams can come true. Nothing has to stay as it is."

Recently Ms Merkel has revealed more details about her movements on the day that the Wall opened.

She told German TV on Saturday that she joined crowds heading towards West Berlin after a visit to the sauna, describing "an incredible feeling of happiness".

The chancellor was joined later at the Brandenburg Gate by former Polish trade union leader and president Lech Walesa and Mikhail Gorbachev, the last Soviet leader.

The anniversary was also mentioned in an address by Pope Francis in Rome.

He told crowds in St Peter's Square: "Where there is a wall, there is a closing of hearts. We need bridges, not walls."
