The urban materialities of disused quarries in Cape Town

Abstract

ABSTRACT Quarried stone has a multitude of uses in the built environment. Often old, abandoned quarries near cities have become enveloped by urban expansion. This paper investigates what becomes of disused quarries, specifically in Cape Town, South Africa. The study is scaffolded by the theoretical underpinnings of urban materiality which, in turn, draws from assemblage theory. It is posited that the urban materialities of quarries, as one-time sites of material extraction, do not cease with closure. The infill, rehabilitation and repurposing of quarries for other uses result in continued contributions of quarries to the urbanscape, in addition to being historical sites of meaning and memory. The location of 77 quarries in Cape Town were mapped using data from various sources. Seventy-one quarries are in a post-extractive state. Thirty-five per cent of disused quarries have not been rehabilitated or altered by human activity after closure. However, they are sites of non-human use. Sixty-five per cent of the post-extractive quarries are sites for housing, commercial and educational activities; for recreational activities; have been infilled; or they store water for agricultural purposes. The reuse of quarries speaks to the creation of new urban materialities and assemblages by humans and non-humans which are worthy of further investigation.
