Castle of the Counts of Benavente

The castle of the Counts of Benavente in the small town of Puebla de Sanabria in the northwest of the province of Zamora is one of the best-preserved castles of the 15th century in Spain.
The castle of the Counts of Benavente is located on a hill about 50 meters high and strategically well-defensible, above the Río Castro, which – along with the Río Tera – surrounds the town of Puebla de Sanabria, situated at an altitude of about 940 to 960 meters above sea level, on three sides. The town and the castle are only about 15 kilometers away from the border with northern Portugal.
