Whitehall is one street with several centuries of power concentrated along its length. Henry VIII built a palace here so sprawling it had its own bowling alley, tennis courts and cockfighting pit. Most of it burned down in 1698, though the Banqueting House survived: a Rubens-ceilinged masterpiece through whose window Charles I stepped to his execution in 1649.

Today the name is shorthand for British government itself. The Ministry of Defence, Foreign Office, Treasury and Cabinet Office all have addresses here, their grand facades hiding the machinery of state. Downing Street branches off behind iron gates. The Cenotaph stands in the middle of the road, forcing traffic to part around it each November when the nation pauses to remember.

VoiceMap's self-guided audio tours trace Whitehall's layers of intrigue, from the spy agencies that once operated in its shadows to the scaffold where a king lost his head.
