The Knight refers to St George's Wharf, the rather swanky development of residential flats with shops, bars and restaurants opposite. The big tower (St George's Tower would you believe) will be the largest residential building in the UK when completed.
The bridge is Vauxhall Bridge. It crosses the River Thames between Vauxhall on the south bank and Pimlico on the north bank. Opened in 1906, it replaced an earlier bridge, originally known as Regent Bridge but later renamed Vauxhall Bridge. It took eight years to build, was the first in London to carry trams and later (1968) one of the first two roads in London to have a bus lane (Park Lane was the other).
The building just over the bridge is the MI6 HQ... can't tell you anymore without having to kill you!!
