Carriage Restorer Dave Evans cleans the 1902 State Landau carriage at the Royal Mews in central London, UK on March 21. The coach will be used to carry Prince William and Kate Middleton on their wedding day, 29 April, as long as the weather is good.

After their wedding ceremony on April 29, Kate Middleton and Prince William will ride in an open-topped 1902 State Landau horse-drawn carriage for the procession back to Buckingham Palace, unless inclement weather leads them to use the famed "Glass Coach," which has a fixed roof to keep rain at bay.

The 1902 State Landau, housed at the Royal Mews near Buckingham Palace, was built for King Edward VII for use at his coronation. It is typically used by the queen to meet foreign heads of state on official visits to Britain. Prince Charles used it to travel to St. Paul's Cathedral for his 1981 wedding, leaving the cathedral with Princess Diana.
