Clashing perceptions of history can be the source of serious divisions in society, but when done well, education can be the best way to convey these complex perceptions of the past. Thus, contested historical sites have immense potential as spaces for teaching, learning and working towards social and historical justice.During the project Contested Histories Onsite, we (virtually) visited four contested sites around Europe (Estonia, Poland, Italy and Spain), highlighting that historical complexity and contestation are universal themes across European societies. For this roundtable, we have invited experts on contested sites to discuss how education and touring can help to overcome these clashes. How can education help in the resignification of the Valley of the Fallen? How are underrepresented histories present in the public space? What can we learn about the history of fascism from the architecture linked to that past? How can we use contested histories as places for research and education? These and more questions will be raised in the roundtable formed by Olivia Durand, Francisco Ferrandiz, Paula O'Donohoe and Hannes Obermair.The Memory Studies Association (MSA) and EuroClio have worked together since 2021 on the Contested Histories Onsite Project with support from the EU's Europe for Citizens Programme.
