Walking round London is always a delight, especially when you spot some of its wildflife … clockwork pigeons in the Museum of London shop, a flock of Elizabeth Frink sheep in Paternoster Square where real pigeons cheekily land on the cafe tables, or even on tourists. A fierce wyvern aka dragon, symbol of the City of London perches on Holborn Viaduct overlooking Farringdon Road, the old Fleet River valley. The river now runs in a huge pipe under the road before emptying into the Thames. You can see the river outfall at low tide from Platform 4 of Blackfriars Station, which I discovered when researching my children’s book Draw It! London
