The World’s Most Famous Door

Your doors are vital to your home. They keep heat and air inside, enhance curb appeal, and provide security.

Some doors, however, hold global significance. They stand as cultural symbols, tell stories, and represent history. One of the most iconic is the door of 10 Downing Street in London—the headquarters of the British Government and the residence of the Prime Minister.

• 1732: King George II gives the property to Sir Robert Walpole, who makes it the official residence of the First Lord of the Treasury.
• 1735: Walpole moves in after three years of renovations, starting a 284-year tradition.
• 1766: Architect Kenton Couse redesigns the door in a six-paneled Georgian style, made from black oak.
• 1770: The door is installed with its signature features: a central knob, lion-head knocker, and brass letter plate inscribed with “First Lord of the Treasury.”
• 1779: The property is officially renumbered as “10.”
• 1908: Prime Minister Herbert Asquith paints the door dark green.
• 1960: The door’s original black color is restored, and new white numerals are added. The “0” is angled slightly, rumored to be a capital “O.”
• 1991: The black oak door is replaced with a blast-proof steel version after an IRA mortar attack.
