Mr Monkey was taken to Blackfriars, where the Millenium Bridge crosses the Thames between St Paul's Cathedral (the big domed thing) and the Tate Modern (the art gallery that looks remarkably like it used to be a power station) on the south of the Thames. Mr Monkey studied the Millennium Bridge with care before stepping on to it.
The Tate Modern website will, unsurprisingly, tell you about the Tate Modern.
