In the ancient times, Iznajar was a prehistoric Iberian settlement. However, the village prospered in the eighth century when Arab settlers built a fortress on the peninsula and called it 'Hins Ashar.' Thus the place now has a modern Spanish name of Iznahar.
Iznajar is to be found in close proximity to the southern boundary of the C province. It also serves as a natural access to the Sierra Subeticas Natural Park. In the recent years, this little village has also metamorphosed into an important area, due to the construction of the reservoir. Also a stunning sight for the visitors to see in this town is the ruins of the 1,200 year old castle.
