The Blue Bridge offers spectacular views across St James's Park Lake to Buckingham Palace to the west and Horse Guards Parade, Big Ben and the London Eye towards the east.
The low-arched concrete bridge is the third to span the lake. The first was designed by John Nash which was replaced by an iron suspension bridge in 1857. The current bridge dates from 1957.
As well as the spectacular views, The Blue Bridge is an excellent spot to view St James's Park's waterfowl.
