The British royal couple visited the statue in Washington DC and also saw the nearby monument to civil rights activist Martin Luther King Jr.

Charles and Camilla stopped at the spot where King gave his iconic "I have a dream" speech in 1963.

The pair were joined on their tour by prominent American civil rights campaigner Jesse Jackson and Congressman John Lewis - both of whom helped organise the civil rights march in Selma, Alabama, in 1965, which was recently recalled in the film 'Selma'.

Afterwards, the couple were given a tour of Mount Vernon, which was the home of America's first president George Washington.

Charles, 66, also took a tour of the National Archives, where he viewed the United States 'Charters of Freedom' and the 1297 version of the Magna Carta - a treaty that is part of the American Bill of Rights and the Constitution that marks its 800th anniversary this week.

The couple are due to meet with President Barack Obama at the White House on Thursday (19.03.15) where they are expected to hold informal talks at the oval office.

Charles and Camilla then conclude their three-day US visit with a trip to Kentucky on Friday (20.03.15).
