The Mall is London’s primary ceremonial road which leads from Trafalgar Square though Admiralty Arch, past Clarence House, to Buckingham palace. The 1km road, which is laid out like a giant red carpet, it is used for royal processions and national celebrations.
The Monarch often receive visiting Heads of State by escorting them in horse drawn carriages up the Mall which would be decorated with Union Flags and flags of the visiting head of state's country.
In 2011 over one million people packed the Mall to see the newly wed Prince William and Kate Middleton appear on the palace balcony with other members of the Royal Family.
Originally laid out by Charles II, the Mall became the grand approach to Buckingham Palace when the palace became the official royal residence on accession of Queen Victoria. The Mall we see today was designed in 1911 by Sir Aston Webb who also designed a new façade for Buckingham Palace, Admiralty Arch and the Queen Victoria Memorial.
Under the Mall is a network of tunnels connecting Buckingham Palace to No 10 Downing Street (the Prime Minister's Office) and the Foreign Office.
Clarence House, part of the St James’s Palace complex, is the official residence of The Prince of Wales, The Duchess of Cornwall and Prince Harry.
Built in 1827 by John Nash it was commissioned by Prince William, Duke of Clarence (King William IV) and has been home to many members of the royal family including; Princess Elizabeth and her husband, The Duke of Edinburgh (now Queen Elizabeth II), the Queen Mother and Princess Margaret. Princess Anne was born there.
Clarence House, along with York House and Lancaster House are within the environs of St. James's Palace and are guarded by soldiers from the Queen’s Household Division when the Monarch are in London.
