LONDON.- The beautifully simple Velodrome in London’s Olympic Park, the carefully crafted remodelling of the Royal Shakespeare and Swan Theatres in Stratford upon Avon, a highly imaginative London school on a tight urban site, an innovative and vibrant cultural centre in Derry, the transformation of an unremarkable 1980s office building in London into an elegant new office and retail space, and the breathtaking extension of a significant museum in Germany, form the shortlist for the prestigious £20,000 RIBA Stirling Prize. Now in its 16th year, the RIBA Stirling Prize in association with The Architects’ Journal and Benchmark is awarded to the architects of the best new European building ‘built or designed in Britain’. The winner will be announced on Saturday 1 October at Magna Science Adventure Centre in Rotherham and will be broadcast on a special edition of BBC Two’s The Culture Show on Sunday 2 October, presented by Kevin M
