The town of Fuentidueña is situated in the far north of the province of Segovia. This natural paradise boasts a strategic location in a narrow valley formed by the River Duratón, which in the Middle Ages afforded it considerable power.

The castle and the Church of San Martín stand at the top of the hill, with the houses huddled beneath on the slope that leads down to the riverbank, extending as far as and even beyond the town walls, which is typical of medieval towns. Other highlights include the medieval bridge over the River Duratón and the Romanesque Church of Santa María. A delightful town boasting a rich history and a stunning natural setting.
