Winston Churchill led Britain through one of the toughest wars in history- the WWII. 

He had made a special underground bunker to carry out his mission. This bunker helped him put his plans into action especially during the Blitz- a series of bombings on London.

Today this bunker is a tourist spot called Churchill War Rooms.

Surprisingly if you notice, the clocks here are set at 2min to 5. This is because, there used to be a meeting here of the Cabinet everyday at 5. The clocks are just a subtle reminder!
