King Charles and Queen Camilla (in a Tiara!) Participate in the Ancient Pearl Sword Ceremony to Mark Coronation

All about the role of the Pearl Sword, first presented to the City of London Corporation by Queen Elizabeth in 1571

King Charles and Queen Camilla are continuing their celebrate the coronation year with historic traditions.

On Wednesday, the royal couple attended a dinner at Mansion House to recognize the work of the City of London's civic institutions and Livery Companies, the city’s ancient and modern trade guilds. The King upheld the traditions dating back to 1689 surrounding a new monarch's first visit to the City of London — the square mile established by the Romans as "Londinium" around 43 A.D. that joins 32 boroughs to make up Greater London — in the coronation year before addressing assembled guests.

While King Charles adorned his suit with various honors and medals, Queen Camilla went full glam in a gown and the Girls of Great Britain and Ireland tiara. According to the Royal Collection Trust, the headpiece was a wedding present from the "Girls of Great Britain and Ireland" to the Duchess of York, later Queen Mary, in 1893. Queen Elizabeth, who was gifted the piece from her grandmother as a wedding present when she married Prince Philip before acceding the throne, wore the tiara throughout her historic 70-year reign and was depicted in the accessory on some British and Commonwealth banknotes and coinage.

Upon their arrival, King Charles participated in the Pearl Sword ceremony. Representing the authority of the Lord Mayor in the City of London, the King was presented with the sword. King Charles then returned the Pearl Sword, confirming the Lord Mayor's authority when the monarch is not present. King Charles' mother, Queen Elizabeth, performed the ceremony in 1953 following her own coronation and again in 1977 and 2022 to mark important jubilees.

Before 1641, the monarch would take the sword for the duration of their visit, but in 1641, King Charles I immediately returned it to the Lord Mayor, a practice that continued ever since. The custom of surrendering the Lord Mayor’s sword to the monarch was first recorded in 1392 when the Lord Mayor offered his sword to King Richard II. The Pearl Sword, adorned with over 2,600 pearls on the scabbard, is believed to have been first presented to the City by Queen Elizabeth I in 1571 for the opening of the Royal Exchange.

The City of London has five swords in total. In addition to the Pearl Sword are the State Sword, the Mourning Sword, the Old Bailey Sword and the Mansion House Justice Room Sword.

Inside the Mansion House, King Charles, 74, and Queen Camilla, 76, had the chance to view the Anointing Screen, which was gifted by the City of London Corporation and City Livery Companies for the most sacred moment of the coronation ceremony, the anointing. The screen combines traditional and contemporary sustainable embroidery practices, and the couple met those involved in the screen’s creation, including its designer Aidan Hart and members of the Royal School of Needlework and the Worshipful Company of Weavers.

The King and Queen then joined a reception where they met representatives of the City of London Corporation, the Common Council, the Livery Companies and the City’s finance sector.

And like many royal engagements, the visit wasn't complete without King Charles and Queen Camilla signing the visitor’s book.
