In 1924 one of two important events which took place was the unveiling by HRH the Prince of Wales of the British Commonwealth Memorial Plaque in Notre Dame Cathedral. He was accompanied by his brother Prince Henry, later the Duke of Gloucester, and the ceremony was conducted in the presence of the President of the French Republic, Monsieur Gaston Doumergues, and Marshal Foch. This started a tradition :

From 1924 onwards, apart from the war years, there has been an Annual Service of Remembrance on November 11^th, which is a national holiday in France. This ceremony is organised by the Royal British Legion (as it became in 1971 when granted its "Royal" prefix), with the generous assistance of the British Embassy Defence Section, A wreath of poppies is laid either at the foot of the altar steps by the British Ambassador together with the Dean of the Commonwealth.

The service is open to British and ommonwealth nationals and anyone else who wishes to take part. It is a most impressive, ceremony and the Cathedral of Notre-Dame is always full. The Service is conducted by The Chaplain of the Paris Branch supported by all the clergy from the English speaking communities in the Paris area. It is essentially ecumenical and the address of welcome is always given by a senior clerical member of the Cathedral.

The British Army supplies a bugler and a piper, who wear full dress, two British Metropolitan Policemen participate in uniform, and most of the French Old Comrades Associations parade their banners as do Associations of the Commonwealth countries and the United States of America.

In 1989 HRH the Prince of Wales, at the conclusion of a State visit to France, attended the service accompaned by HRH the Princess of Wales. He read the lesson and, supported by the British Ambassador, laid the wreath.
