Torrelobatón Castle is one of the most important and best-preserved fortresses in Valladolid. In the historical epic film El Cid with Charlton Heston the castle played the role of Vivar, hometown of El Cid.
The castle was begun in 1406, when Don Alfonso Enríquez, 1st Admiral of Castile, obtained licence from John II to erect a fortress in Torrelobatón; the only fortification there was a modest stone enclosure surrounding the village. The castle was involved in the Revolt of the Comuneros against Charles I (Holy Roman Emperor Charles V).
It has a square ground-plan, with circular turrets at three of the corners and the keep set into the fourth, protecting the gate. The castle was surrounded by an enceinte, of which there are some remains, and a ditch, now mostly filled in. The entrance to the Torrelobaton Castle courtyard is through a gate with a round-headed arch protected by a portcullis. The keep is the most interesting feature of the fortress. Of considerable height, the upper part is protected by eight turrets supported on accordion brackets, one at each corner and one in the middle of each wall.

Sigmaringen Castle was first mentioned in the year 1077 in the chronicles of Petershausen monastery. The oldest parts of the castle are concealed beneath the alterations made during the 17th and the 19th centuries. The secret of the earliest settlement built on this defendable rock will never be fully revealed: large-scale excavation work would be necessary, which the extensive land development renders impossible. Judging from the many Roman remains unearthed in the area around Sigmaringen, the 12th century keep known as the 'Roman Tower' could be traced back to a Roman predecessor.
The castle remains that have been preserved (gate, great hall and keep) date back to the Staufer period around 1200. The castle remains were integrated into subsequent buildings. The foundations of the castle buildings are to a large extent identical to the surrounding castle wall.
These remains give us a good idea of how the castle might have looked during the 12th century.
