The OWO is a majestic and fully licensed setting for the most spectacular London weddings and civil ceremonies.
The Old War Office was home to legends. Today, the stage is set for a new chapter as this historic landmark becomes The OWO, an exciting new destination in the heart of Whitehall and peerless venue for every occasion. From weddings in the spectacular Whitehall Ballroom and cocktail receptions in The Lawrence, to meetings in the versatile Morse and Code rooms, every event benefits from the finest Raffles service. Enjoy afternoon tea with a Mediterranean twist, courtesy of three-star Michelin chef Mauro Colagreco in Saison. Or a traditional afternoon tea in The Drawing Room. And discover the fascinating history of the building during our heritage tours on certain days across the year. See London from a new perspective at The OWO.
