As I had to go into London today I went in a bit early and stood on a near deserted Waterloo Bridge and took this. See if you can spot all the landmarks - I'll give you a few to start off, scanning from the left, although you may need to zoom in a bit... St Pauls, The Gerkin, Monument (if you look really hard), a hazy Canary Wharf, The OXO Tower, The Shard, IBM, Royal Festival Hall, County Hall, The London Eye, Palace of Westminster, Somerset House, Cleopatra's Needle.
