The documentation, curation, and dissemination of endangered architectural heritage requires multidisciplinary expertise and imaginative engagements with heterogeneous formats and scales of analysis. Through a case study of a Carpathian-style chapel in Beaver, Pennsylvania, St. Nicholas Chapel, we explore how an architectural heritage building might be interactively documented in a way that situates it within long-standing architectural traditions while remaining attentive to its social and material specificity. We present a prototype of an interactive document showcasing a multi-modal and multi-scalar approach to architectural heritage that innovatively brings together data-intensive typological analyses, historical documentation, ethnographic interviews, geometric studies, and photogrammetry and LiDAR captures. The web-based document offers a highly detailed portrait of the St. Nicholas Chapel, inviting a broad audience of users to dynamically explore it through a combination of high-quality imaging and scanning methodologies, artificial intelligence (AI)-enabled geometric analyses, historical materials, and first-person accounts of its construction.
