Palenzuela
Palenzuela stands above the valleys of the Arlanza and Arlanzón, its castle and walls guarding a settlement with deep roots in the history of Castile. A medieval charter recorded the villages of its district and the rights of a nearby monastery over pastures and woodland. The town later served as a royal residence and as the centre of the Cerrato district. During the reign of John II, the Cortes met here, reflecting the importance Palenzuela still held in the fifteenth century.
