Princess Anne unveiled a commemorative plaque to mark 100 years of a French school in South Kensington.

HRH The Princess Royal launched the centenary year of the Lycée Français Charles de Gaulle on Thursday (May 21).

She was joined French Ambassador to the UK, Sylvie Bermann, and the Director of the Agency for French Education Abroad, Hélène Farnaud-Defromont.

Ms Bermann said: “It is an honour to welcome HRH The Princess Royal to celebrate the 100th birthday of the Lycée Charles de Gaulle.

“For a century, the school has helped foster cultural links between France and the UK, and The Princess Royal’s presence at the centenary celebrations is testament to the important role it plays.”

The Lycée Français Charles de Gaulle de Londres is celebrating its 100 years with a series of cultural and festive events taking place in May and June at its South Kensington site in Cromwell Road, involving current pupils, members of staff and the school’s Old Students’ Association.

It includes an exhibition charting the Lycée’s history, concerts and theatre performances.

The day after the royal visit (May 22) the school opened its doors to the public, allowing pupils past and present to meet and share their experiences and memories.

The Old Students’ Association is also marking the year with the publication of a special book commemorating the history of the school, entitled Le Lycée Français Charles de Gaulle de Londres 1915 – 2015. The book will be on sale throughout the year.

Earlier in the week, members of the royal family including The Queen were in town to visit The Chelsea Flower Show.
