The aim of this article is to explore new ways of integrating technology, nature and infrastructures into urban public spaces. This is done through a case study, the design of General Vara del Rey, which is offered here as a model to explore a novel urban political ecology that calls into question dominant definitions of public spaces as self‐contained sites operating independently of natural and infrastructural spaces. Through the double movement of ‘the technification of public space’ and ‘the publicization of infrastructures’, the square aims to rethink the political ecology of urban public spaces by enabling the effective incorporation and participation of infrastructural and natural elements as active actors into the public and political life of the community. It is argued that the transformation of infrastructures into fully visible, public and political agents provides a useful model to address the growing proliferation of infrastructural and technological elements onto contemporary urban surfaces and to open up the possibility of new forms of civic participation and engagement.
