Cuenca (Castile–La Mancha) -

When the Iberian peninsula was part of the Roman Empire, there were several important settlements in the province, such as Segobriga, Ercavica and Gran Valeria. However, the place where Cuenca is located today was uninhabited at that time. When the Muslims captured the area in 714, they soon realized the value of this strategic location and they built a fortress (called Kunka) between two gorges dug between the Júcar and Huécar rivers, surrounded by a 1 km-long wall. Cuenca soon became an agricultural and textile manufacturing city, enjoying growing prosperity.
