(Bloomberg) -- Chancellor Angela Merkel urged Europe to fight harder for its values as Germany marked 30 years since the fall of the Berlin Wall on Saturday.

“The values on which Europe is based -- freedom, democracy, equality, the rule of law, safeguarding human rights -- these are anything but self-evident,” Merkel, who grew up in communist East Germany, said in a speech at the wall memorial in the center of the once-divided capital.

“They must be experienced and defended anew again and again,” said the 65-year-old. “In times of far-reaching technological and global change, this is more relevant than ever.”

German President Frank-Walter Steinmeier, Bundestag President Wolfgang Schaeuble and heads of state from Poland, Hungary, Slovakia and the Czech Republic also attended the ceremony.

“The Berlin Wall is gone and that teaches us that no wall that excludes people and restricts freedom is so high or so wide that it cannot be broken through,” Merkel said.
