Since 1995, the International Conference on Structural Analysis of Historical Constructions (SAHC) has been recognized as a leading international event dedicated to the study and protection of heritage structures. The conference serves as a meeting point for researchers and practitioners from diverse disciplines, fostering discussion on the multifaceted challenges, innovative methodologies, and materials pertinent to these goals. The 14th edition of SAHC was held in Lausanne, Switzerland, from 15 to 17 September 2025. This edition was the largest in the history of the series, bringing together nearly 600 participants from more than 50 countries, reflecting the growing global interest in the protection of heritage structures. Over the past decades, our field has reached high technological and scientific standards across various disciplines. It is now widely acknowledged that the preservation of heritage structures requires a multidisciplinary approach encompassing historical investigation, inspection, structural analysis, intervention, and monitoring. During SAHC 2025, more than 450 presentations addressed these topics, showcasing the latest advancements in the field. A closer look at the contributions revealed a clear trend: the digital era is no longer on the horizon — it has arrived. Nearly half of the submissions incorporated digital tools, underscoring the conference theme “Heritage Conservation in the Digital Era.” This signals an important message — our field is evolving, embracing innovation, and shaping the future of heritage protection through digital transformation. SAHC 2025 was a collective success made possible by the contributions of many individuals and organizations. Our gratitude goes to the Scientific Committee and Reviewer Panel for their rigorous evaluation of the submissions; the Advisory Committee for their guidance from nomination to the organization of the conference; the Special Session Chairs for proposing and curating timely, relevant topics; the Session Chairs for fostering engaging discussions; the sponsors and supporting organizations for their generous assistance and promotion of the event; and the members of the Earthquake Engineering and Structural Dynamics Group at EPFL for their support throughout the preparation and delivery of the conference. Above all, we thank all authors for sharing their experience and knowledge with our community. This volume comprises the extended abstracts presented during the conference. The full papers have been published in a separate publication by the RILEM Bookseries. We wish you an enjoyable reading of the conference proceedings and look forward to seeing you at future editions of the SAHC conference.
