The Landmark London is a five-star hotel on Marylebone Road on the northern side of central London, England, in the City of Westminster. It was originally opened by the Great Central Railway, as the Hotel Great Central. As one of London's railway hotels it declined after the advent of the motor car, and served as a military convalescent home during the Second World War, and later the headquarters of the British Railways Board. It reopened as a hotel in 1993.
