Churchill War Rooms, London (must see)

Tucked beneath the former Office of Public Information—now the Treasury—lies one of London’s best-kept “open secrets”: the Churchill War Rooms. This covert bunker was the nerve center from which Winston Churchill directed Britain’s wartime efforts... and occasionally napped in his bathrobe.

Hidden right under Clive Steps on King Charles Street, the entrance is so discreet you might walk right past without noticing it. In fact, the Nazis never guessed that Britain’s emergency government was cheekily hiding in plain sight, just 12 feet below London’s crust. For comparison, Hitler himself was holed up a paranoid 180 feet underground. Overcompensating, perhaps?

Built in 1938 and retrofitted as the war heated up, the War Rooms were reinforced with a “bomb-resistant” ceiling. Emphasis on resistant, not bomb-proof, which made every thunderclap a bit more thrilling for those working below. Spanning 30,000 square feet, the facility came equipped with everything from conference rooms to bedrooms, because a good nap is crucial for strategic warfare...

When the war ended, everyone simply left. No cleanup, no moving out, just poof—gone. Clocks are still frozen at 4:58 pm, marking the first wartime Cabinet meeting in 1940, and the calendar in the Map Room eternally reads August 16, 1945—the day Japan surrendered. It's like time hit “pause” and never came back.

You’ll see phones with odd green handles—high-tech marvels of the 1940s known as scrambler phones. They took 20 minutes to warm up and blasted white noise like an angry seashell. Eavesdropping? Not on Churchill’s watch.

Meanwhile, the walls are studded with pinholes from frantic map-stabbing, some patched so many times they now qualify as historical patchwork quilts.

Churchill himself only spent a handful of nights here, but he used the bunker frequently—for meetings, cigars, and power naps in less-than-Prime-Ministerial attire. One of the highlights is a fire bucket turned ashtray, where he’d casually discard cigar stubs. Enterprising Marine guards allegedly sold those stubs to souvenir hunters. Recycling and capitalism at their finest.

Rumor has it there’s a second, even deeper bunker underneath, full of pipes, cables, and possibly Churchill’s wine cellar. Sadly, not open to the public—yet...
