Goring Hotel

The Goring Hotel was opened by Otto Richard Goring on 2 March 1910 and professed to be the first hotel in the world in which every room had a private bathroom and central heating. In 1914, The Goring became the command centre for the Chief of Allied Forces, and contact with President Woodrow Wilson during World War I was made from this hotel. In November 1917 it became the U.S. Army Headquarters in London, as it was adjacent to the American Naval and Military authorities. The hotel was released back to its owners on 8 September 1919.
In 1919, Lady Randolph Churchill, the mother of Winston Churchill, moved into The Goring Hotel. During World War II, Fox Film stayed at the hotel.
