Welcome to 10 Downing Street — perhaps the most famous front door in the world. This modest black-bricked townhouse has served as the official home and office of the British Prime Minister since 1735, when King George II gifted it to Sir Robert Walpole, the first to hold the office. Walpole commissioned William Kent to merge it with a grander house behind, creating the maze of elegant rooms, offices, and cabinet chambers still in use today. Over the centuries, it’s been a home, a command centre, and a stage for world affairs — from Churchill’s wartime councils to Barack Obama’s 2009 visit. Once nearly abandoned amid Whitehall’s grime, it was restored to splendour and remains the beating heart of British politics — where history is still written behind one very famous black door. But before we move on, let’s recall that cigar-wielding giant — Winston Churchill.
