Thousands of people gathered on Sunday evening in front of Berlin's Brandenburg Gate for an open air event held as part of celebrations marking the 25th anniversary of the night the Berlin Wall fell.
The event was attended by German Chancellor Angela Merkel and other officials, and performers included English musician Peter Gabriel.
A million people were expected to attend Sunday's festivities in Berlin, which included the open-air party at the city's Brandenburg Gate and the release of hundreds of helium-filled balloons strung along a 15-kilometre (9-mile) stretch of the former border.
At least 138 people died at the Wall during its 28-year existence, and hundreds more were jailed for trying to escape.
On the night of November 9, 1989, thousands of East Berliners streamed through the once-closed border crossings, after communist authorities caved in to mounting pressure and relaxed travel restrictions that had prevented their citizens from going to the west for decades.
The fall of the Wall was the climax of weeks of popular protests, spurred by changes that had already taken place elsewhere in Eastern Europe.
