The green, triangle-shaped expanse of leafy land just beyond the Ritz is Green Park. Penned in at two corners by St James’s Park and Hyde Park, it was enclosed by Charles II in 1668 as a hunting ground before opening to the public in 1826.
Every year millions of Londoners and tourists visit The Green Park, the smallest of the capital’s eight Royal Parks.
Comprising just over 40 acres of mature trees and grassland next to Buckingham Palace, the peaceful triangle between Piccadilly and Constitution Hill offers a popular location for picnics and sunbathing in fine weather.
