EURAU is a network of schools and researchers in Architecture and Urbanism, which meets biannually in a symposium to share their investigations. EURAU's main concern is to establish these meetings as a place of debate and discussion of contemporary discourses in Architecture, City and Town Planning. This is a committed action organized by University and contributes with the Europe 2020 Strategy towards a smart, sustainable and an inclusive society. The French Ministry of Culture initiated EURAU in 2004. Since then, a series of international editions have taken place and now with the participation of hundreds of researchers from around the world, it is impossible to stop. The series organized by different Schools of Architecture have been around the themes. The School of Architecture at Alicante University organizes EURAU18 with the theme RETROACTIVE RESEARCH: Architecture’s capacity to challenge and extend the limits of other disciplines.
