The next bridge downstream is... by Pegasus74
The next bridge downstream is London Bridge which isn't gonna fall down anytime now. The original was bought and transported stone by stone to the Arizona desert where it still stands today. The latest incarnation of the bridge is a three-span construction opened in 1972, which spans securely now. Tower Bridge, the best known Thames span was where I ended my stroll along Thames' south bank. It reflects the Victorian obsession with Gothic architecture. The lowest bridge of all that spans the Thames, it is still raised to allow tall ships through. Today's opening mechanism is electrified as opposed to the original mechanism which uses hydraulic machinery. As dusk gives way to night, the floodlit bridge is especially spectacular as it stands against the night sky of the capital.
Cross the Thames to the north bank here to the Tower of London. This Norman castle was where many famous and notorious prisoners of the Crown met a grisly end. Today it is home to the Crown Jewels.
