Berlanga
Berlanga de Duero lies beneath a castle on a height above the Escalote valley. In the early sixteenth century its lords built a new artillery fortress around the older medieval stronghold, while also developing a palace and gardens below. In 1529 the sons of Francis I of France were held at Berlanga as hostages during the rivalry between their father and Charles V. The town was also the birthplace of Tomás de Berlanga, a Dominican who became bishop of Panama.
