Military bands could be heard practising ahead of the procession while street cleaners were working with precision to ensure the area in front of the palace was ready.
People attending the coronation service began filing into Westminster Abbey at just after 7.30am.
Dozens poured into the church wearing suits, fascinators, military uniforms and medals and religious clothing.
Sniffer dogs had been patrolling the area shortly before the guests filed in to the Abbey.
