While in Berlin last weekend, I attended the opening of the exhibition Die Stadt. Vom Werden und Vergehen (The City. Becoming and Decaying) at C|O Berlin in partnership with Ostkreuz. The exhibition features photography by 18 Ostkreuz photographers who have 'embarked on a search for the essence of present-day urban realities'. It was a long-term project that covered 22 cities around the world, depicting urban growth and decay. The exhibition runs until 4 July. Above image: Pactrick B.
