Through a closer reading of diverse contemporary sources, this paper provides an insightful investigation of Prince Taz unique palace that stands majestically at the heart of Medieval Cairo. It casts light on the historical significance of this palace where successive layers of the past (Mamluk, Ottoman and Khedival) meet with the present and merge harmoniously together. Due to the absence of any catalogue of the palace, the paper also seeks to provide tour-guides with the essential information they direly need to know while arranging guided-tours inside it. Over and above, the paper aims at valorizing this long-shrouded heritage that was miraculously restored in recent years, nevertheless it remains on the edge.
