Grosvenor Square in the heart of Mayfair in London has often been called ‘Little America’, although it actually takes its name from the Grosvenors, the family who own the land there. It is where the first American Consulate in Britain was found, the consul being John Adams, who later became America’s second president. He was a Founding Father, and the wish to establish cordial relations with the former enemy nation is part of the reason he moved to a house in Grosvenor Square at the corner of Brook and Duke Streets, one which still stands.

On the afternoon of 7th September 1940, 350 German bomber planes attacked London, devastating the docks area and killing over 400 people. The day became known as Black Saturday and marked the beginning of a bombing campaign – the Blitz – that terrorised the city for eight months. Around 20,000 Londoners were killed. Eighty years on from Black Saturday, Blue Badge Tourist Guide Ruth Polling explores how remnants of that period can still be seen in London today.
