This paper develops an account of post-war London from the building site paintings of Frank Auerbach and Leon Kossoff. It approaches these paintings as a visceral and embodied source of data regarding the post-World War Two landscape of bomb damaged London. It contrasts this form of knowledge with the narratives of memorialization, and order and control, which I argue characterize post-war reconstruction. In this context the paintings are read as an ontological statement about the complexity and ambiguity of the urban landscape, one which contrasts with historical and contemporary narratives of the urban built environment. The paper posits that knowledges which preserve the complexities and materialities of urban space have the potential to provide political interventions into both historical and contemporary narratives of the city.
