Bridget Kendall talks to Patrick Keiller about the relationship between film, cities and landscape. Victoria Henshaw is interested in what our cities smell like, and what we lose when we sterilise our environment. The poet Robin Robertston has written about the bleak, remote island of St Kilda and how the remnants of its close-knit community left together in 1930. The importance and difficulty of creating a sense of community is at the heart of Giles Fraser's new series which asks whether we've become merely nostalgic for a bygone age of close neighbourhoods, or whether it's possible to reconstruct them.
