Its maximum width extending from the southern shorelines to the northern shorelines is 7.5 km (4.7 mi) (the distance between Gomrok Port and the lighthouse). The island’s surface is flat, lacking mountains or even high hills. Kish International Airport is built in the center on an elevated area 35–40 m (115–131 ft) above sea level.
In the shadow of the empire, the islands in the Gulf became prosperous, navigation in the Persian Gulf was expanded, and better vessels were used to carry passengers and goods. Navigational aids, including lighthouses, were set up to facilitate navigation in the Persian Gulf.
