Ian McMillan and his guests explore writing and cityscapes, asking how does architecture make us think about the writing process, and how do language and cities refresh each other – or use each other?Joining Ian are the novelist Jenny Colgan on the City of Invention (which the late novelist Fay Weldon uses to describe literature in her book Letters to Alice: On First Reading Jane Austen); by skateboarder and poet Olly Todd on his new collection Out for Air; by the writer and novelist Reinier de Graaf, who explores the corporate language of architecture (and the need for all new buildings to be 'officially amazing'); and the poet Geraldine Monk, who shares a brand new commission - part of our BBC centenary series Something Old, Something New.
