Home To Legends

Raffles London is located in what was once the Old War Office building, known today as The OWO. It was once home to legends, such as Sir Winston Churchill and Lord Kitchener and Haldane, Sir Mansfield Cumming, T.E. Lawrence otherwise known as Lawrence of Arabia. The list of who walked the halls goes on. Ian Fleming, creator of James Bond, conjured up his famous espionage novels from his time spent working here. Many scenes from the 007 movies have been filmed on location at The OWO – a nod to the author’s past.

The OWO is associated with spies and espionage, as MI5 and MI6 had operations here during the 20th century. Located in the heart of Whitehall, the building has been meticulously restored and home to Raffles London at The OWO.
