The Royal Mews is an important branch of the Lord Chamberlain's Office and provides road transport for The Queen and members of the Royal Family by both horse-drawn carriage and motor car. It is also one of the finest working stables still in existence, responsible for the training of the Windsor Greys and Cleveland Bays, the horses that pull the royal carriages.
State vehicles are housed and maintained at the Royal Mews. They include the carriages used for royal and State occasions, such as State Visits, weddings and the State Opening of Parliament. Carriages from the Royal Mews are also used on roughly 50 occasions each year to convey newly appointed High Commissioners and Ambassadors from their official residence to Buckingham Palace to present their credentials to The Queen. Since 1843 the daily messenger Brougham has set out from the Royal Mews to collect and deliver post between Buckingham Palace and St James's Palace. The most dazzling of all coaches housed in the Royal Mews is the Gold State Coach, which has been used at every coronation since that of George IV in 1821.
