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 ancient Argos Theater was built in 320 BC. and is located in Argos, Greece against Larissa Hill. Nearby from this site is Agora, Roman Odeon, and the Baths of Argos. The theater is one of the largest architectural developments in Greece and was renovated in ca 120 AD.
The Hellenistic theater at Argos is cut into the hillside of the Larisa, with 90 steps up a steep incline, forming a narrow rectilinear cavea. Among the largest theaters in Greece, it held about 20,000 spectators and is divided by two landings into three horizontal sections. Staircases further divide the cavea into four cunei, corresponding to the tribes of Argos A high wall was erected to prevent unauthorized access into the theatron and may have helped the acoustics, but it is said the sound quality is still very good today.
Around 120 CE, both theaters were renovated in the Roman style.
