UK architect Sir David Chipperfield has won the Mies van der Rohe award for his renovation of the mid 19th century Neues Museum in Berlin.
The prize is sponsored by the European Commission, the executive body of the EU.
The restoration of the Neues Museum, which was badly damaged in the Second World War, involved reconstruction of a missing wing in a stripped-down style.
Chipperfield left the 19th-century painted walls of the museum as they were, allowed bullet holes in the walls to remain and made new interventions including the construction of a dramatic grand staircase and a free standing concrete structure.
The other competitors for the prize included Zaha Hadid for the Maxxi Museum in Rome, Bernard Tschumi for the Acropolis Museum in Athens and Jean Nouvel’s Concert House in Copenhagen.
