The story behind THE London picture

Tower Bridge is synonymous with London. Most people, if asked, might say it was built of stone, but you can see clearly in this shot that the stone is just cladding around the Victorian cast iron heart. The lifting bridge could not have been stone, and it goes up and down maybe once a day or so. But there's something else a little interesting here. The walkway at the top is almost as if the Victorians anticipated tourism. But, when it was built, that was not the reason. The Pool of London docks was so busy back then, that road traffic might be blocked for an hour a time. So, they built in the walkways to allow pedestrians to go about their business. Times have changed.
