The castle of the Rojas is located on the top of a hill near the town of Poza de la Sal. At the end of the 9th century Count Diego Rodríguez Porcelos repopulated Poza building the castle for the defense of the new territory. Like other castles of this time it may have been a simple keep surrounded by some walls.
In the 14th century Rodriguez de Rojas family rebuilt the current castle. It was occupied in 1808 by French troops and was a target of continuous attacks of Burgos garrisons until the end of the war.
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.
