Walking is one of the most sustainable and healthy forms of everyday travel over short distances, but pedestrianism has declined substantially in almost all countries over the past century. This paper uses a combination of personal testimonies and government reports to examine how the spaces through which people travel have changed over time, to chart the impacts that such changes have had on pedestrian mobility, and to consider the shifts that are necessary to revitalise walking as a common form of everyday travel. In the nineteenth century, most urban spaces were not especially conducive to walking, but many people did walk as they had little alternative and the sheer number of pedestrians meant that they could dominate urban space. In the twentieth century successive planning decisions have reshaped cities making walking appear both harder and riskier. Motorised transport has been normalised and pedestrianism marginalised. Only radical change will reverse this.
