’Castle of Peñaranda de Duero.’
The castle of Peñaranda (Burgos province), set on a hill just north of the Duero, was originally part of the 9th-11th century Moorish defense line against the Christians along this river. In the 10th century it was taken by the latter and was used as a centre of Christian repopulation on the northern margin of the Duero. The river (and the castles along it) formed the southern border of the Kingdom of Castile till the second half of the 11th century. Peñaranda Castle was rebuilt in the 15th century.
