It is increasingly recognised that cartography is a contested practice
, embedded within particular sets of power relations, and that maps ar
e bound up with the production and reproduction of social life. The au
thor begins by emphasising the importance of these issues for consider
ing how the city has been mapped and represented through cartographic
schemes, and draws on debates around the power and politics of mapping
, and contentions that maps are 'preeminently a language of power, not
of protest'. However, it is argued that maps and mapping have not bee
n entirely the preserve of the powerful, and the main part of the pape
r is devoted to examining some specific challenges to 'official' carto
graphies of the city. The author focuses on the radical art and politi
cal group, the Situationist International, and its avant-garde predece
ssors of the Lettrist International, who sought to appropriate urban m
aps and cartographic discourses and to develop a new form of 'psychoge
ographical mapping' during the 1950s and 1960s. The paper provides an
account of their subversions, and an assessment of how their concerns
might inform contemporary discussions on cartography and the mapping o
f urban space.
