Neither the origins nor the date of construction of San Romualdo Castle is certain, although historians are fairly sure that this castle dates back to medieval times. Built in the Mudéjar style, it was first mentioned in 1268. It is thought to have been used as both convent and fortress.
The castle was officially declared as a historic monument by the Spanish authorities in 1931 and is easily located near the town centre, half way between the town hall and the Zuazo Bridge.
References: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.
