The new lighting system for Tower Bridge, one of the world's most well known landmarks, has been officially switched on.
After weeks of testing at 9pm on Wednesday 30th May 2012 the new energy efficient lights illuminated the famous London icon for the first time.
At first the bridge was swathed in a dazzling white but as darkness descended on the Thames the bridge and its towers was ablaze with a range of colours including the patriotic red white and blue of the Union Jack national flag.
Tourists and Londoners alike stood and watched the display and at 10pm the bascules of the bridge were raised to allow the MV Dixie Queen to pass through into the Upper Pool of London, sounding her horns in celebration as she did so.
The unveiling comes just days before the Queen's Diamond Jubilee and in time for the London 2012 Olympic and Paralympic games.
They’re among the most famous unsolved murders in history, and the mystery continues to deepen. Suspects for the shadowy figure who came to be known as Jack The Ripper have ranged from an itinerant Polish labourer to the eminent Victorian doctor Sir William Gull, and even the painter Walter Sickert. But another theory has emerged – that is the chilling suspicion the person who carried out the 1888 murders was actually a woman. Author John Morris puts forward his suspicions in the book Jack The Ripper: The Hand Of A Woman. As a result of extensive research by Morris (and his late father, who was equally fascinated by the riddle) he believes the only satisfactory conclusion is that Jack was, in reality, a woman.
