Germany marks 50 years since Berlin Wall
Germany is marking 50 years since the building of the Berlin Wall when the communist East closed its border, dividing the city for 28 years.
Berlin Mayor Klaus Wowereit told a ceremony on Bernauer Street: "The Wall is history but we must not forget it." President Christian Wulff said Germany had been securely established as a reunified country. The city observed a minute's silence at noon (10:00 GMT) in memory of those who died trying to escape. Soldiers from the East began construction on the morning of 13 August 1961. The BBC's Stephen Evans in Berlin says the East German authorities portrayed the Wall as a barrier to keep the fascist West out - what came to be known as the Anti-Fascist Protection Rampart. But he says the accepted view now is that it was to keep East German potential migrants in. 'Saddest day' Addressing the ceremony on Bernauer Street, famously divided by the Wall and now site of a memorial, Mayor Wowereit said the capital was remembering the "saddest day in its recent history". "It is our common responsibility to keep alive the memories and pass them on to the next generation, to maintain freedom and democracy and to do everything so that such injustices may never happen again," he said. At a ceremony at a former crossing-point, President Wulff said the wall had been "an expression of fear" of those who created it. "The world situation, of which this wall was a symbol, seemed irreversible to many people," he said. "But this was not the case. In the end, freedom is unconquerable. No wall can survive the will for freedom in the long term. The violence of just a few has no hold over the drive for freedom of many." Chancellor Angela Merkel, who also attended the event, was herself raised in the East. The number of people who died trying to cross the Wall is disputed - at least 136 are known to have been killed but victims' groups say the true number is more than 700. The first victim was thought to be Guenter Litfin on 24 August 1961 and the last Chris Gueffroy on 6 February 1989. A list of names of the victims was read out overnight. Although the Wall came down in 1989, it remains for some a symbol of continuing economic division between the richer west and poorer east. Invisible barrier Brigitta Heinrich, a schoolteacher by profession, grew up in Klein-Glienicke, which was unusual in that it was an East German enclave on the territory of West Berlin. Speaking to Russian news agency Ria-Novosti, she said one of her own pupils had escaped across the Wall in the early days, using a ladder. The schoolboy's parents were forced to move out of Klein-Glienicke as a result, and the mother was sacked from her job in a company, she said. Recalling the hardships and broken illusions of the communist state, Ms Heinrich, who still lives in the East, also talked of the difficulty of readjusting to a unified country. She said she had made friends with other Europeans such as Italians and Finns since the fall of the Wall but some West Germans, especially in regions further away from Berlin, seemed indifferent to people from the former East, as if an invisible barrier remained. "I cannot name a single West German with whom I socialise now - really, I can't," she said. Few parts of the Wall remain, though city authorities have laid down an 8km (five-mile)row of cobblestones to mark its path. Tourists often struggle to find original sections.
