This paper introduces a method to enrich multi-layered, multi-phase 3D models of cultural heritage with art history knowledge. This is achieved through imagebased annotations, interactive narratives, points of interest, text, and audio, creating guided tours of the monument's historical phases. The approach is user-friendly for art historians, requiring no programming skills for defining such elements. A pilot user evaluation demonstrated its effectiveness in enhancing visitor engagement and understanding, and allowed improving the final web-based application and narratives.Attribution 4.0 International LicenseCCS Concepts: Computing methodologies → Computer graphics; Applied computing → Fine arts; Human-centered computing → Visualization design and evaluation methodsComputing methodologies → Computer graphicsApplied computing → Fine artsHuman centered computing → Visualization design and evaluation methods10.2312/gch.202412477 pages
