Grosvenor Square has been the traditional home of the official American presence in London since John Adams established the first American mission in 1785. He used to live at No 9.
Also known as ‘Eisenhower Platz’ during World War II when Dwight Eisenhower established a military HQ at No 20.
The square is home to a number of US Monuments, including that of Franklin D Roosevelt, the Eagle Squadrons Memorial and a 9/11 memorial.
It also used to house the US Embassy from 1960, although this has been moved to brand new premises in Battersea. The current building is to reopen as a Rosewood Hotel once the remodelling has been completed.
