This Sunday marks 25 years since the fall of the Berlin Wall so we decided it was a fitting time to mention the fragment of the wall which accompanies the bronze statue of former US President Ronald Reagan in Grosvenor Square, Mayfair.

The remnant of the wall, recorded as taken from the “east side”, can be seen through a window in a bronze plaque which commemorates the role President Reagan played in the coming down of the wall.

The plaque also features quotes from President Reagan – including the famous line from his 1987 Brandenburg Gate speech, “Mr Gorbachev, open this gate. Mr Gorbachev, tear down this wall” – and other figures including former UK PM Margaret Thatcher and Mikhail Gorbachev as well as information about the wall itself.

In a dedication to the president, it further reads: “Ronald Reagan, the 40th President of the United States of America, was a principled fighter for freedom. With a clear vision and will, he gave hope to the oppressed and shamed the oppressors. His contribution to world history in the 20th century, culminated in his determined intervention to end the Cold War. President Reagan has left a lasting legacy as a campaigner for global peace.”

The memorial was unveiled on 4th July, 2011, outside the US Embassy by the Ronald Reagan Presidential Foundation, to mark the 100th birthday of the former president. Among those present at the unveiling of the statue were then Foreign Minister William Hague and former US Secretary of State Condoleezza Rice.

There are also larger sections of the wall outside the Imperial War Museum in Lambeth and in the National Army Museum in Chelsea (closed for redevelopment until 2016).
