So the plan was, originally, to wander from City Hall, beneath Tower Bridge, and around Shad Thames.
None of my images from Shad Thames worked at all. And it certainly didn't help that one hand of the street was draped in scaffolding, but oh well - I still came away with these.
This part of the Southbank is a perfect juxtaposition, the clean, modern, glass edges of Foster and Partners' More London Riverside; separated by the gothic bascules of Tower Bridge from the converted imperial warehouses of Shad Thames; narrow iron bridges linking them above street level. It's a haven for City workers and tourists alike, but I highly doubt anyone really stops and admires both the design, and how quiet a place so close to the centre of everything can be.
Without sounding pretentious, it's very much aesthetic.
