London is a river city. Bridges are central to its character and have always played an important role in my knowledge of the city. I have always lived in areas served by Waterloo, which basically means crossing the river to get anywhere. And walking is normally the best option . To get somewhere, to know a place, to form a mental map. At dusk the balance of light on St Paul’s and the bridge is balanced by a bit of deep blue in the sky. Urban and punchy yet relatable.
