The Greek cities hold a broad base of the religious, civil, war, educational, commercial, and funeral architectural styles. Thus, it is a good opportunity for the researchers in Islamic architecture and civilization, in general, and the Ottoman, in particular, to bridge many historical and architectural gaps. The researchers have neglected and disregarded the monuments of the Ottoman Empire in Europe, especially after the collapse of the Ottoman Empire in the European part. It was deliberate neglect inspired by racism in some European countries. They sometimes tended to carelessness or direct destruction. Consequently, less than (10 %) of the original monuments have survived, as shown in the books of travelers and statistics by the Ottoman authorities. The remaining monuments, even a few, are important for understanding and identifying the characteristics of Ottoman architecture and the arts in the European cities, especially Rhodes. Fortunately, this Island still holds hundreds of Ottoman monuments. The mau-soleums and cemeteries are among the most significant resources in identifying the Ottoman architectural styles and patterns in Rhodes. They help form a complete picture, not only architecturally and technically, but also demographically as well as nature, names, titles, and occupations of the Ottomans at that time.
