The "Augmented Thresholds: Sustaining Architectural Heritage of Istanbul Land Walls (a(TRH] Vol 1) event, organized by Istanbul Technical University (ITU) with support from the Erasmus+ Blended Intensive Program (BIP), will take place via online seminars (March-June 2025) and in-person workshops in Istanbul (July 19-27, 2025). Approximately 40 participants, including academics and undergraduate/graduate students from six uni- versities will come together for this event. The aim is to develop an interdisciplinary approach to preserving the Istanbul Land Walls and ensuring their sustainable future. The workshops will explore topics such as the digitalization of historical architectural and archaeological heritage, the integration of gamification methods, examining the Land Walls at environmental, urban & landscape scales, evaluating architectural elements from a circular economy perspective, and reinforcing the Land Walls as a thresh- old in historical, functional, and temporal contexts. This comprehensive event aims to strengthen international cooperation while offering new approaches for the preservation and transfer of an important cultural heritage site, such as the Istanbul Land Walls, to the future.
