Several months ago, some of my colleagues in Japan launched an online portal through which it is possible to explore from one’s own office the complex of the Mamluk sultan Qalawun (d. 1290), in Cairo (see: Qalawun VR Tour or the project’s site). In this post, I will present a brief overview of the portal so that readers may familiarize themselves with the concept behind the site and may seek further examples and opportunities to produce similar sites.
