The public are to be encouraged to take a close look at the construction process in 'Construction Sights' - a project commissioned by Leeds City Council and co-ordinated by arts agency Pavilion. It runs from 6 April to early August in conjunction with work on Leeds' new Millennium Square. Architect Pierre d'Avoine, photographer Debbie Baker, and video artist Michael Pinsky are the principal collaborators. The square will be built in front of Leeds' Civic Hall (top left). On the steps of the hall, at present off-limits to the public, a viewing platform will give an overall view of the site as it evolves, with information about its past and future (top right). A new hoarding, painted in a polka-dot pattern (above left), will be pierced with 100 'spyholes'. Some of these will look directly onto the site (above right); through others spectators will either see Baker's portraits of Leeds residents or, on microscopic video screens, a work by Pinsky. Additional events, involving the square's architect John Thorpe among others, will take place over the summer.
