Green Park is London's most unadorned royal park, and that's entirely the point.

Its 47 acres contain no formal flowerbeds, no lakes, no bandstands. Just grass, mature trees, and deckchairs. The reason for this botanical austerity varies depending on whom you ask: some say Charles II's wife demanded the flowers be ripped out after catching him picking a bouquet for another woman. Others point to its past as a leper burial ground. Neither story is true, but both are more interesting than the real explanation, which involves soil drainage.

The park forms a green corridor between Piccadilly and Buckingham Palace, its eastern edge lined with the grand townhouses of aristocratic London. The Canada Memorial near its centre honours the million Canadians who served in both World Wars.
