This paper aims at contributing to the debate on university teaching in the era of Covid-19. It presents the experience gained in 2020 at the Politecnico di Milano while teaching Architectural Preservation on both the international and Italian track. The students worked on the medieval fortress of Arquata del Tronto, an emblematic case study of the fragility that characterizes the territory of inner Italy and its resilience. The building has indeed survived the earthquake that devastated the Apennines in 2016, and today, it watches over the reconstruction process. The paper discusses the risks and opportunities of this experience.
