The former mayor of Tewkesbury, councillor John Martin, first introduced the riversidewalk idea in 1949 as a means of regenerating the town after the war.
Bleak grey terraces have sprouted gardens, and music and markets enhance a new riversidewalk from Vauxhall to Tate Modern (where a rather unpleasant 20-foot anatomical sculpture by Damien Hirst now greets visitors approaching the museum).
