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.

The Odeon of Herodes Atticus is a stone theatre structure located on the southwest slope of the Acropolis of Athens. It was built in 161 AD by the Athenian magnate Herodes Atticus in memory of his wife, Aspasia Annia Regilla. It was originally a steep-sloped theater with a three-story stone front wall and a wooden roof made of expensive cedar of Lebanon timber. It was used as a venue for music concerts with a capacity of 5,000. It lasted intact until it was destroyed and left in ruins by the Heruli in 267 AD.
The audience stands and the orchestra (stage) were restored using Pentelic marble in the 1950s. Since then it has been the main venue of the Athens Festival, which runs from May through October each year, featuring a variety of acclaimed Greek as well as International performances.
