The abandoned buildings of the Cold War

What buildings are left over from the Cold War? Acclaimed Dutch photographer Martin Roemers made it his task to track down these relics. From 1998 to 2009, Roemers criss-crossed Europe, from England to Russia. Along the way he photographed former military bases, abandoned war bunkers, deserted training areas and military cemeteries. This exhibition in Berlin also places these structures in historical context. Different sections explore the arms race, the threat of a third world war and the role of spying and intelligence. Relics of the Cold War runs at the Deutsches Historisches Museum until August 14. For more information visit www.dhm.de.

Paul Strand was a gifted American photographer and filmmaker, who set the gold standard for documentary work.

This exhibition in London presents a major retrospective of his work, with about 200 pieces on display. Included are examples of his strikingly candid street portraits from Italy in the 1950s, along with his more experimental work in abstraction.
