London's Grosvenor Square begins the Grateful Dead song "Scarlet Begonias" ("From the Mars Hotel", 1974, lyrics by Robert Hunter, music by Jerry Garcia): "As I was walking round Grosvenor Square." On Wikipedia, I found information about literary references to it, and its history. For example, Oscar Wilde lived there in 1883-1884, and his Dorian Gray lived nearby. In World War Two, when General Eisenhower had his HQ there, it was nicknamed "Eisenhower Platz". In 1968, anti-Vietnam War demonstrations took place there outside Eero Saarinen's US Embassy building (built in 1960). — But I wonder if any Londoners (or others in the UK) can tell me what associations Grosvenor Square has for them.
