Cian O’Callaghan and Cesare Di Feliciantonio will host a workshop on the IRC-funded project “The New Urban Ruins: Vacancy and the Post-Crisis City” from 1-3 March in Trinity College Dublin. This workshop proposes will explore how contestations over the reuse of vacant spaces can be used to think about cities and urbanisation in new ways. Topics covered include the central role that vacancy played in recent property crashes, debates about urban shrinkage, the popularity of new approaches to temporary urbanism, and critical discussions of ruins. The central hypothesis is the vacant space will play a key role in determining how cities of the future respond to the both urban problems and wider global challenges. Keynote speakers include Dr. Christina Lee (Curtin University, Perth Australia), Prof. Karen Till (Maynooth University, Ireland), Dr. Alexander Vasudevan (Oxford, UK).
