The Heart of London
Raffles London at The OWO


1906
The New War Office, designed by British architect, William Young, was opened on Whitehall to house 2,500 government and military officials. It was built in Edwardian Baroque style and it had over 1,000 rooms and 2.5 miles of corridor. King Edward VII (the eldest son of Queen Victoria) was monarch when it opened.
The New War Office was the centre of the British Army's administration and it is from this building that Sir Winston Churchill helped mastermind the Allied Victory over Hitler.
