Pre-dawn preparations have taken place, as up to a 1,000 members of the Army, Navy and RAF participated in a full walk through and dress rehearsal, in advance of the Royal Wedding.
All the members of the Armed Forces involved in the wedding were on parade at 4.30am, dressed in full ceremonial uniform, to march along the route. Horses and carriages also took part in the pre-wedding procession to Westminster Abbey.
The Abbey closed its doors to the public on Tuesday so that preparations for the wedding could begin. A music rehearsal will take place on Wednesday and a full dress rehearsal for clergy on Thursday.
The eyes of the world will be on Prince William and Catherine on Friday 29 April 2011.
