Wandering London's streets, as I often do, I am still surprised by the extraordinary things hidden in plain sight.
Take the railings, in the photo above. At first glance they appear to be your standard railings, which are quite often found south of the river, in places like Bermondsey, Brixton, Camberwell, Deptford, Southwark, etc.. There even some north of the River Thames, in Poplar.
However, these are no ordinary railings. They are almost 80 years old and once served a very different purpose.
During World War II many of the metal fences and railings, around various houses and buildings, were removed, so that the metal could be used for the war effort.
