Lifting the secrets of Tower Bridge attracts 350 curious visitors

An incredible look behind the scenes to see how Tower Bridge works attracted 350 visitors during a series of exclusive weekend tours.

History and engineering enthusiasts were given a unique insight into areas normally closed to the public.

These included the Bridge Control Room, the immense Bascule chambers below the level of the river bed and the Victorian engine rooms which house the restored steam pumping engines and hydraulics that powered the lifting of the bridge until 1976.

Only 12 visitors at a time could be taken around the workings of London’s most iconic landmark.

The tours which ended last week also included the famous high-level walkways with their panoramic view 140ft above the Thames.

Tower Bridge first opened in 1894, built by Sir John Wolfe-Barry, the top civil engineer of his day. It has become one of the world’s most recognised icons, synonymous with London—the largest and most-sophisticated bascule bridge ever built when it was completed.
