The Ottomans were quickly developing urban cities upon their conquest of B&H, enriched by Islamic and Byzantine influences. For example, in Foča in the 16th century, the Ottomans built 17 mosques, 29 public fountains, 6 public baths ("hamam") and 13 caravanserai motels (han). Sarajevo is an example of a non-urban open city where the most important buildings are organized around one veining street, a "čaršija" (Persian chahar-su meaning all four sides). In Sarajevo the largest is famous Baščaršija with shops of 50 different crafts from the 15th century.
