The German Chancellor, Angela Merkel, is in Hungary to mark the 20th anniversary of the country opening its borders to the non-communist West.
The decision paved the way for the fall of the Berlin Wall three months later.
The open Hungarian border with Austria allowed hundreds of East Germans to leave communist Eastern Europe.
The event on 19 August, 1989, was called the "Pan-European Picnic". Merkel, who grew up in East Germany, said she wanted to thank Hungary.
She praised the Hungarian people for what she called their courage and foresight.
Organizers of the "picnic" like Laszlo Nagy had wanted to highlight the division between East and West. They did not plan the outcome, but it exceeded their expectation.
