Sixty-four Freemasons who won the Victoria Cross during the First World War, have been honoured at a ceremony in London today.
Their names have been inscribed on paving-stones outside the organisation's UK headquarters.
Freemasons Hall London was built to honour more than 3,000 masons killed in the First World War.
Today, guests all came together to watch a ceremony celebrating valour of the men who earned the Victoria Cross during the 1914-18 conflict, and who also happened to be Masons.
The Duke of Kent, the Grand Master of Masons, was in attendance as the stones containing the 64 names were then unveiled.
The Band of the Grenadier Guards Provided the musical accompaniment to the spectacle, which took place in the tercentenary year of the United Grand Lodge of England, the English and Welsh governing body for freemasonry.
As freemasons conduct some of their rituals in secret, speculation and rumour about who they are is not uncommon.
