Newton at the British Library

Designed by Eduard Paolozzi from Leith, involved with the pop art movement of the 1950's, it was inspired by William Blake's depiction of the same guy (pictured on the right). You'll find the British Library along the Euston Road from King's Cross/St Pancras (a must-see itself).

Black Cats

Guarding the entrance of the Greater London House (formerly the Carreras Tobacco Company) in Mornington Crescent, Camden these 7 feet high, bronze cats were presumably modelled on the Gayer-Anderson statue of the ancient Egyptian goddess Bastet. The factory they look after opened in 1928, just 8 years after the discovery of Tutankhamen's tomb in 1920 and is said to be inspired by the temple of Bubastis. The Carreras company produced Black Cat cigarettes (geddit?) in the early to mid 1900s.

Golden Boy of Pye Corner

This little fella was erected at the corner of Giltspur Street and Cock Lane in Smithfield to mark the spot where the fire of London stopped. He's a symbol of gluttony as that's why the fire is supposed to have started in the first place (divine retribution indicated by the fact that the fire started in Pudding Lane and ended at Pye Corner).

Animals in War Memorial

This is a lovely idea - a memorial to those creatures who didn't really have much of a choice in whether or not to give their lives for the war effort. The Portland stone wall depicts all sorts of animals, birds and even glow worms who did their bit (the glow worms were used in the trenches to read maps by). Eight million horses for example, are thought to have died during the course of the First World War alone. The memorial was designed by English sculptor Dave Backhouse and made possible by a fund inspired by Jilly Cooper's book Animals in War You'll find it on Park Lane beside Hyde Park.
