While advanced technologies such as virtual reality (VR) and augmented reality (AR) enhance experiential depth for specialized audiences, literature identify intuitive navigation, coherent content organization, and strategic multimedia integration as critical drivers of sustained user interaction. The portals, developed via WordPress CMS with custom plugins and support for multiple languages, emphasize accessibility, inclusivity, and multilingualism to broaden reach. Analytical data spanning several years reveal that niche content differentiation limits audience scalability, underscoring the need for enhanced SEO strategies and supplementary contextual materials. The findings offer actionable insights for developers and researchers aiming to optimize digital platforms for cultural heritage preservation and global engagement.Attribution 4.0 International LicenseCCS Concepts: Applied computing → Digital libraries and archives; Architecture (buildings)Applied computing → Digital libraries and archivesArchitecture (buildings)10.2312/dh.202530174 pages
