Like your Royal Family large? The largest ever photograph of Queen Elizabeth II, her husband, the Duke of Edinburgh, and their four children has been displayed on South Bank building, Sea Containers, in celebration of the Queen’s Diamond Jubilee. The iconic picture of the family – which also includes Earl Mountbatten, uncle to Prince Philip, and Princess Anne’s then husband Mark Phillips – was taken during 1977’s Silver Jubilee by an unknown photographer. The 100 by 70 metre image, which weighs nearly two tons, took eight people more than 45 hours to put into place on the building’s facade overlooking the Thames. It was erected by the owner of Sea Containers as a tribute to be seen during this weekend’s Jubilee Flotilla (and also to hide development work taking place behind as the building is transformed into a Mondrian hotel – Europe’s first – and office space.

This week we start a new series in honour of this year being the Diamond Jubilee of Queen Elizabeth II. We’ll be looking at locations across the city which have played an important role in the story of the Queen. First up, it’s the Queen’s birthplace – a now non existent townhouse in Mayfair.

The property at 17 Bruton Street, which is marked by a small plaque installed in 1977 – the Queen’s Silver Jubilee (it’s in the middle of the image to the right), was actually the home of the Queen Mother’s parents, the Earl and Countess of Strathmore. It and the neighbouring townhouse at 18 Bruton Street have both been demolished and replaced with a rather bland office building.

Born here at 2.40am on 21st April, 1926, the Queen, named Elizabeth Alexandra Mary, was the first child of the then Duke and Duchess of York (later King George VI and Queen Elizabeth). At her birth, Queen Elizabeth II was only third in line to the throne after her uncle, the Prince of Wales (later, briefly, King Edward VIII), and her father.

The Queen’s grandparents, King George V and Queen Mary, both visited the newborn child at the property (along with an apparently large crowd outside). Elizabeth was christened five weeks later at the Chapel Royal in Buckingham Palace. She spent the first few months of her life living in a room at 17 Bruton Street which had been previously used by her mother before her marriage.

Recent books on the Queen include Andrew Marr’s  The Diamond Queen: Elizabeth II and Her People, the souvenir album Queen Elizabeth II: A Diamond Jubilee Souvenir Album, and Sarah Bradford’s Queen Elizabeth II: Her Life in Our Times.
