British architect Zaha Hadid has won the 2011 Stirling Prize for her design of a London school building, the Evelyn Grace Academy. She also won the award last year for the MAXXI Museum of 21st Century Arts in Rome. The award, now in its 16th year, is intended to recognise the best European building designed or built in Britain.
