Standing behind those famous black railings on Whitehall, 10 Downing Street might look modest from the outside, but don't let appearances fool you. This Georgian townhouse has been the epicenter of British political power for nearly three centuries, and honestly, there's something quite thrilling about being so close to where history gets made daily.

I've walked past those iconic gates countless times, and while you can't actually stroll down Downing Street anymore – security put an end to that in the 1980s – you can still get a decent view from Whitehall. The famous black door with its simple brass number 10 is probably one of the most photographed entrances in the world, though what you see from the street is just the tip of the iceberg.

The building itself dates back to the 1680s, designed by Christopher Wren, and it's far larger than it appears. Behind that narrow frontage lie around 100 rooms spread across multiple floors, including the prime minister's private residence on the third floor. The real surprise is the half-acre garden at the back – a proper oasis in central London that most people never suspect exists.

What strikes me most is how this place has witnessed everything from Winston Churchill's wartime leadership to the pivotal decisions that shaped the British Empire. Every prime minister since Robert Walpole in 1735 has called this home, and the walls have absorbed some truly momentous conversations. The current resident, Sir Keir Starmer, continues this long tradition, along with Larry the cat, who holds the official title of Chief Mouser to the Cabinet Office.

The security presence is obvious but not overwhelming, and I've found that timing your visit matters. Early morning or late afternoon tend to be less crowded, giving you a better chance for photos without tourist hordes. While you can't take a traditional tour, the exterior viewing is completely free and accessible any time.
