Pictures of the week: London’s Square Mile, by Polly Braden

Polly Braden began photographing the Square Mile of London in 2006, fascinated by the way that this City within the city operates. With its own Lord Mayor and independent police force, the Square Mile is something of an oddity, and Braden’s photographs pose the question, “What is this space in the middle of our city?” Read more

The stretched middle: can Londoners cope with hundreds of new towers?

London’s relatively clear skyline, once dominated by St Paul’s Cathedral and, later, by Canary Wharf, the Gherkin and the Shard, is likely to get an awful lot more crowded over the coming years, with almost 250 tall towers proposed, approved or already under construction. Read more

The New York subway photographs of Christopher Morris

This atmospheric series depicts the chaos and squalor of New York’s subway system in 1981, in all its graffitied glory. The then 22-year-old Christopher Morris – these days best known for his war photography – was interning at a photo agency. “I was new to New York, at the very start of my career, and I became mesmerised by the total urban decay, that was most visual with the subway system.” See more

A really spectacular image … those clouds looks rather portentous and the way the light is breaking through at the heart of the frame seems almost apocalyptic. It was taken over Victoria harbour in Hong Kong, in case you’re wondering. From picture desk live: best news images of the day

The city of Shanghai (right) sits along the delta banks of the Yangtze river along the eastern coast of China. It is the world’s most populous city (the 2010 census counted 23 million people, including “unregistered” residents). With so many humans, the city is a tremendous sight at night. The bright lights of the city centre and the distinctive new skyscrapers that form the skyline along the Pudong district (the eastern shore of the Huangpu river, a tributary of the Yangtze that cuts through the centre of Shanghai) make for spectacular night viewing both on the ground and from space. On the left is Suzhou located 120km from Shanghai
