The külliyye built by Sinan set the pattern for other külliyye architects. Most külliyye followed these patterns: they were "located at the important points of the city" and the structure emphasize the religious center of the mosque. In addition, they were either "built on hills and sloped lands, coasts or peripheries of the city".[2] The reason for this is that külliyye helped create the silhouette and landscape of the city.
